Pull, no push
“Somos buenos para hacer el pull, no el push. Pull es jalar, push es empujar. Cuando hemos intentado vender, salió mal. Lo que sabemos hacer es hacer un post y traer atención, no empujar: cómpreme esto, cómpreme esto.”
“We're good at pull, not push. Pull is drawing in, push is shoving out. When we've tried to sell, it went badly. What we know how to do is make a post and draw attention, not push: buy this, buy this.”
Claude's channel analysis confirms a self-knowledge Juan already felt. They're good at pull, a post that attracts, a viral chart, a Reddit thread, this very podcast, and bad at push, direct selling, which failed last year. The strategic read: lean into the pull channels where they're strong (visualizations, Reddit, vertical video) and treat selling as a separate learning curve rather than the default motion. Know which motion you're good at, and build the plan around it instead of against it.
El lector ciego
“No existe una buena solución para que un ciego pueda leer cómics. No existe. Lo que hacen es meterle imágenes a ChatGPT, muy manual, cuadrito por cuadrito. Esa es una de las ventajas de Koby.”
“There's no good solution for a blind person to read comics. It doesn't exist. What they do is feed images to ChatGPT, very manual, panel by panel. That's one of Koby's advantages.”
Focusing Koby on the blind niche, a possible blue ocean, because no good tool exists for a blind person to 'read' comics, the manual workaround is pasting each panel into ChatGPT and rebuilding the prompt every time. Koby would have Gemini describe the images (ten free daily, since the API isn't free), add a read-and-listen mode and a free library, anticipating that even downloading a book is harder for a blind user. But reaching the community is itself hard: Julia's r/Blind post to test the idea was silently deleted under a rule against asking questions or soliciting user info unless you're backed by a named institution.
El truco del dominio
“Si tú ya tienes un dominio, la renovación es mucho más cara porque ya le tienes cariño. Hostinger vende dominios a un peso porque sabe que te va a dar pereza cambiarte. El truco es pedir que cambien el DNS a Cloudflare o Porkbun, que solo cobran la renovación base, como la mitad.”
“If you already have a domain, the renewal is much more expensive because you're already attached to it. Hostinger sells domains for one peso because it knows you'll be too lazy to switch. The trick is to ask them to move the DNS to Cloudflare or Porkbun, which only charge the base renewal, about half.”
Hostinger lures you with a near-free first year, then jacks the renewal (they were charged 70,000 pesos against a ~30,000 average) betting you won't bother moving, because losing the domain means updating every link across luarai.com, Koby, and Severo. The trick is to transfer the DNS to Cloudflare or Porkbun before renewing, since those charge only the base renewal. Related: subdomains can rank fine (Google itself uses docs.google.com) and save the cost of renewing extra domains. A small defense against vendor lock-in built on your own inertia.
Solución en busca de un problema
“Hay que intentar no ser una solución en busca de un problema, sino lo contrario: buscar una problemática real y resolverla. Hagan la búsqueda primero, busquen en comentarios de Facebook, Reddit, blogs, de gente que diga 'por qué no existe esto', y ahí es donde uno construye el producto.”
“You have to try not to be a solution in search of a problem, but the opposite: find a real problem and solve it. Do the research first, look in comments on Facebook, Reddit, blogs, from people saying 'why doesn't this exist', and that's where you build the product.”
The runway-out reckoning. For months they built on their own feeling, I think the app should have this, and when users finally arrived they didn't grasp the value. The lesson learned late: don't be a solution in search of a problem; do the deep research first, real complaints on Reddit, Facebook, blogs, then build the fix. Even the new reading app, once published, revealed competitors in the comments ('I did this a while ago'), a saturated red ocean the research would have shown up front. Obvious in hindsight, and yet not.
El sisbén
“Si a uno le pasa alguna emergencia y no tiene salud, se la meten, puede salir muy alto. Nos contaron de un amigo sin salud que llevaron al hospital, lo dejaron bien, pero después llegó una factura de 10 millones.”
“If some emergency happens to you and you don't have health coverage, they get you, it can come out very high. They told us about a friend with no coverage who was taken to the hospital, they patched him up, but then a 10-million-peso bill arrived.”
A year without health coverage as broke entrepreneurs. Fellow entrepreneur friends who'd been through it told them to register for SISBEN, the state safety net you qualify for at zero income: a utility-bill copy plus IDs, then an interview asking your income (zero). Nobody plans to use it, but a single uninsured emergency can run into the tens of millions, so it's pure prevention, mejor prevenir que lamentar. (Follow-up in v268: they got classified, but Sanitas' page quietly shunts independents and pensioners to a government page while welcoming employees.)
El login anónimo
“Tenemos login anónimo, que es buena práctica para que no haya una pared. Pero el problema del login anónimo es que la persona no tiene la necesidad de dejar de ser anónimo. Nunca sé cuál es el correo, nunca sé quién es, nunca sé qué le gusta o no le gusta.”
“We have anonymous login, which is good practice so there's no wall. But the problem with anonymous login is that the person has no need to stop being anonymous. I never know their email, never know who they are, never know what they like or don't like.”
Guest login lowers the entry wall, better a guest than someone who bounces off a signup form, but it hides the user, so Juan can't email them, can't ask for feedback, can't learn what they like. His patch is incentives (coins, a streak freeze) plus reminders to nudge people into registering and revealing an email. The dilemma is that the same low wall that gets people in also keeps them anonymous and unknowable, and people are leaving even before they reach the anonymous login.
La proteína falsa
“Hace como cinco meses no tomamos más proteína, solo creatina, y siento que he crecido mucho. Muestra que tal vez la proteína en polvo es algo falso: con una alimentación buena no necesitas tanta. Escogimos entre comida o proteína, y para mí la comida es lo más importante.”
“For about five months we haven't taken protein anymore, just creatine, and I feel I've grown a lot. It shows that maybe protein powder is a bit of a false thing: with a good diet you don't need that much. We chose between food or protein, and for me food is what matters most.”
Money forced a choice between food and protein powder, and they chose food, a tub of protein is ~150,000 pesos for a month and a half, while ~150,000 buys two months of a fruit market for two. Juan kept growing on food and creatine alone, which he reads as evidence that the supplement is oversold once your diet is decent. A small nutrition heuristic against a marketed default: real food over the powder, when you have to pick one.
El costo de hacerse viral
“Después del primer día que publiqué, me llega la cuenta de la API a 150.000 pesos en un día, cuando el mes iba en menos de 20.000. Agradezco que no se haya hecho 100% viral, porque ahí sí fácilmente un millón o más, y es plata que por ahora no podemos perder.”
“After the first day I posted, the API bill hits 150,000 pesos in one day, when the whole month had been under 20,000. I'm grateful it didn't go 100% viral, because then it'd easily be a million or more, and that's money we can't afford to lose right now.”
Exposing the IPA service to Reddit brought about 30,000 views of traffic, and the API bill spiked from double-clicks and bots (reCAPTCHA later flagged ~5.5% of requests as suspicious). He fixed it with caching, so each click no longer regenerates the request, plus reCAPTCHA. The lesson: a semi-viral moment has a cost, and an unprepared endpoint with no cache and no rate limit can drain you fast, so being spared full virality was a blessing right up until the defenses were in place.
Prompts contradictorios
“Una de las causas principales de las alucinaciones eran prompts contradictorios: decirle en una instrucción 'ponga esto' y en otra 'no, ponga esto otro'. Es como decirle 'responda feliz' y a la vez 'responda triste'. Está haciendo dos cosas al mismo tiempo.”
“One of the main causes of the hallucinations was contradictory prompts: telling it in one instruction 'put this' and in another 'no, put this other thing'. It's like telling it 'answer happy' and at the same time 'answer sad'. It's doing two things at once.”
Chasing the language hallucinations in Severo, where it would start teaching Spanish to someone learning English, Juan found the main cause wasn't the model but the prompt: contradictory instructions pulling it two ways at once. Once the contradictions were removed, Spanish-to-English, and any language into English, worked cleanly, with only a few edge cases left. The fix for a model that seems to hallucinate is often not a smarter model but a prompt that stops quietly asking for two opposite things.
El coworking que nadie alcanza
“En Chía las únicas oficinas de coworking están al frente de Fontanar o atrás de la Universidad de la Sabana. Para la gente de Chía no es factible, termina siendo lejos. Sin carro no es cómodo para el día a día.”
“In Chía the only coworking offices are across from Fontanar or behind Universidad de la Sabana. For people from Chía it isn't viable, it ends up being far. Without a car it isn't convenient for the day to day.”
Two entrepreneur friends open a coworking in central Chía, in an old call-center space with a cheap lease, near the town hall and on the bus route. The gap they're filling is quiet but real: coworkings already existed, but sitting where locals couldn't reach them daily. A service can exist and still be unavailable to the people who need it, if it isn't where they are, the same accessibility catch as a wholesaler that requires a car. The underserved local market is often not an absence of the service, but a mislocation of it.
Tu problema no es único
“Uno se da cuenta cuando emprende que puede que uno piense que su problema es una pendejada que nadie más tiene, pero realmente mucha gente más lo tiene.”
“You realize, when you're building something, that you might think your problem is some silly thing nobody else has, but really a lot of other people have it too.”
Their fig tree gives more fruit than they can use, so Juan photographed it and posted to r/whatshouldicook asking for recipes, expecting little. The post drew ~45,000 views, 172 comments, and a flood of recipes (Fig Newtons, baked with blue cheese). The realization is the reusable one: the trivial private problem, what to do with too many figs, or the discovery that IPA is a huge learning aid, turns out to be shared by a crowd the moment you publish it. When you build, you assume your itch is unique; publishing it is how you find out it isn't.
El sesgo del slop
“Cualquier cosa en Reddit que la gente piense que fue escrita por ChatGPT, de una vez dislike, aunque realmente todo está escrito por ChatGPT hoy en día. Es ese tipo de sesgo que uno tiene pero que se volvió involuntario, el sesgo del slop.”
“Anything on Reddit that people think was written by ChatGPT, instant dislike, even though everything is written by ChatGPT these days. It's that kind of bias you have but that became involuntary, the slop bias.”
A good post gets buried the moment someone comments 'written by ChatGPT', and giving that comment a reply only hands it visibility so others pile on the downvotes. Juan admits he carries the same involuntary aversion, a heartwarming animal video now leaves him feeling defrauded, and notes that AI has become a buzzword flung at everything (a former mentor called an image-search algorithm 'AI'), the way 'internet' was a buzzword twenty years ago. The tool's overuse has produced a reflex suspicion of the label itself, whether or not the work is any good.
El Casio
“Sentía que no estaba controlando muy bien mi tiempo, que el tiempo vuela. Y nada, tenía que buscar una solución. Me compré ese reloj.”
“I felt I wasn't controlling my time very well, that time flies. And so, I had to find a solution. I bought that watch.”
Juan trades the Rolex-dream for a ~60,000-peso Casio, not for the price but for the function: a cheap watch on his wrist makes the passing of time visible again, since without it he loses track. The first days felt strange, sleeping with it, the way a new necklace makes you hyper-aware of your neck. It's a small move against the same time-pressure that Kanye's accident and One Piece's timing keep circling, turning an invisible thing, time slipping away, into a constant physical signal you can't ignore.
La ilusión del rodízio
“La sensación de comprar algo por más es como, uy, voy a comer más, a pesar de que es falso. Normalmente acabas comiendo tal vez un 10% más porque tu estómago tiene un límite. Para mí siempre vale más algo condensado, que te ofrezca mucho valor en menos tiempo.”
“The feeling of buying more is like, oh, I'll eat more, even though it's false. You normally end up eating maybe 10% more because your stomach has a limit. For me, something condensed is always worth more, giving you a lot of value in less time.”
Choosing a movie sparks a debate about perceived value. Julia's instinct is the all-you-can-eat one, an unlimited buffet (rodízio in Brazil) feels like more value even though your stomach caps you at roughly ten percent extra, so a two-and-a-half-hour film feels worth more than a ninety-minute one. Juan's counter is that condensed value beats volume: what matters is how much a thing gives you per unit of time, not its length, and a bloated six-hour film of nonsense proves the point. It's the same reasoning behind their own long diary videos, more in one place, and the same trap, mistaking quantity for worth.
La interfaz que muestra avance
“Duolingo con los modulitos da esa vibe de satisfacción, como de estoy avanzando, estoy mejorando, estoy aprendiendo. Y precisamente eso es algo que no teníamos con la interfaz anterior. Era como perdido, ¿para dónde voy, de dónde vengo?”
“Duolingo, with its little modules, gives that vibe of satisfaction, like I'm advancing, I'm improving, I'm learning. And that's exactly what we didn't have with the old interface. It felt lost: where am I going, where am I coming from?”
Juan had wanted to keep Severo's home screen minimalist, one Play button straight into an exercise, but felt something missing he couldn't name. The analytics and the dogfooding gave it a name: the old screen was efficient but directionless, and users couldn't see what they'd done or where they were headed. Copying Duolingo's hexagon-module path (the good 2014 version) added the one thing a Play button can't, a visible sense of progress. Efficiency put you into the work fastest; the map is what makes the work feel like it's going somewhere.
La altura de China
“En 34 años la altura promedio de los hombres de China subió de 1,67 a 1,75. Es el resultado de todo el tema de la nutrición, de cómo China ha mejorado. Yo creo que es el país que más ha sacado personas de la pobreza.”
“In 34 years the average male height in China went from 1.67 to 1.75. It's the result of the whole nutrition question, of how China has improved. I think it's the country that has pulled the most people out of poverty.”
An infographic of average male height by country, 1985 to 2019, becomes a small lesson in reading development off the body. China's jump is the standout, the visible result of nutrition improving as it lifted the largest number of people into the middle class, while India rose far less and the Netherlands looks like it hit a ceiling. Height is a legible proxy for a nation's prosperity; the stereotype of the short Chinese man is a snapshot of a poverty that a generation of better food has quietly rewritten. (Side note from the same clip: the creator first drew it in inches and Reddit made him redo it in centimeters before it took off.)
No linealidades
“Está relacionado con una cosa que se llama no linearidad: cómo un sistema puede salirse del equilibrio cuando ciertos factores se ponen en juego. Los sistemas van dando señales de a poquito, pero pueden resultar casos en que se rompe y no da aviso.”
“It's related to something called non-linearity: how a system can leave equilibrium when certain factors come into play. Systems give little signals bit by bit, but there are cases where it breaks and gives no warning.”
After loading heavy calf raises at the gym, Juan got a violent, unprecedented case of the chills, stretching cold near midnight, shaking he couldn't stop until he got under the blankets, and days later still felt off. Gemini's explanation, muscle microtears, blood rushing to the strained legs, thermal shock, led him to the idea of non-linearity, which he ties to a bridge that collapsed under a passing motorcycle. A system leaves equilibrium abruptly when several factors combine, sometimes after giving small signals nobody read, sometimes with no warning at all.
El bebé que hace señas
“Por alguna extraña razón los bebés adquieren mucho más rápido el lenguaje de señas que a hablar. Pero si tu ciclo social solo usa señas, ¿para qué hablar? Ahí puede salir el tiro por la culata.”
“For some strange reason babies acquire sign language much faster than speech. But if your social circle only uses signs, why speak? That's where it can backfire.”
Prompted by a video of a signing baby and by Koko the gorilla, who signed, asked for a cat, cared for it, and mourned it when it died. Early communication is a real advantage: a baby can express hunger or cold before it can speak, and learning faster early compounds, the way math prodigies read more by age five than a teenager. But the same head start can delay speech if the environment never demands it, a child whose family only signs has no reason to talk, another double-edged prodigy, like the child geniuses who paid for the early start with no childhood.
La burbuja gringa
“El gringo que nunca ha salido del país es muy mente cerrada. Nosotros somos la mejor nación del mundo, todo el mundo debería saber de fútbol americano. Ellos piensan que todo el mundo sabe, pero la realidad es que no.”
“The gringo who's never left the country is very closed-minded. We're the best nation in the world, everyone should know American football. They think everyone knows, but the reality is they don't.”
Sparked by a viral clip of an Italian streamer in Japan confronted by a visiting US athlete over a misheard word, this becomes a note on how offense is cultural, not universal. Juan's read: the US exports its media and assumes the world shares its taboos, so a word whose weight comes from US slavery history, taboo outside Black-to-Black use, lands very differently on a Japanese speaker echoing a song lyric or on the streamer who simply said 'amiga' to someone off-camera. Reported as an observation on cultural context and the closed-mindedness of never leaving your own bubble, endorsing nothing about the word itself. Contrast: Europe, small and full of immigrants and languages, tends to read a struggling foreigner more generously.
Retornos decrecientes
“Las aplicaciones bien hechas están llenas de esos detallitos chiquiticos, y por eso, en mi expectativa, esta vaina ya debería estar volando el primer mes. Pero cada cosita que agregamos es un detallito que hay que mirar cómo.”
“Well-made apps are full of those tiny little details, and that's why, in my expectation, this thing should already be flying in the first month. But every little thing we add is a detail you have to figure out how to get right.”
Juan reaches for the concept of diminishing returns to explain why Severo isn't taking off yet. Like a painting, three strokes give you the concept and every later touch adds real but shrinking value; a week of vibe-coding got Sanfanson to a nice MVP, but the last ten percent is a long tail of tiny fixes. The invisible ones cost most: a week refining the Stanza backend, work nobody sees unless it's broken, or a save-word button that sits where the listen button used to, a small thing that still has to be right, because well-made apps are made of exactly those.
La fase cero
“Hay un hueco gigante que yo llamo la fase cero. Si tú no dominas la base, que es el alfabeto, no sabes ni cómo se pronuncia, miras solamente dibujos, eso es nada para ti.”
“There's a giant hole I call phase zero. If you haven't mastered the base, the alphabet, you don't even know how it's pronounced, you're just looking at drawings, that's nothing to you.”
A blind spot surfaces as they head toward launch: Severo is roughly 99% built for Latin-alphabet languages. Testing a non-Latin one, Chinese, Korean, Japanese, Hindi, Arabic, Russian, would expose the missing 'phase zero', the point before A1 where a learner can't yet read the script at all. The cautionary example is the Duolingo commenter who finished the Arabic course and never learned to read Arabic, only memorized 'the man eats the apple'. The alphabet is the prerequisite the whole curriculum silently assumes.
No hay edad para romperla
“No hay edad para el éxito, no hay edad para romperla. Usted la puede romper con 40, 50, 60 años. Pero hoy se vende mucho la idea de que si no lo lograste joven, ya eres un fracasado.”
“There's no age for success, no age to break through. You can break through at 40, 50, 60. But today they sell hard the idea that if you didn't make it young, you're already a failure.”
The Ney Matogrosso biopic shows his fame arriving after thirty, and Juan reads it as a rebuttal to a story the media keeps selling. Sensationalized young prodigies, the Olympic skater everyone praises, a teenager already at a top football club, push people to feel like failures by thirty. His counter: Ney broke through past thirty, Bad Bunny too, so no age caps a breakthrough, and the child prodigies often paid for it with no childhood, their whole free time spent training. Sports may be the exception, bound by a body's useful life, but in music the late bloomers prove the point.
El héroe del sistema
“Si tú estás en un sistema que piensa que todo esto está bien y que te recompensa, y lo haces creyendo que vas a ir al cielo, ¿por qué no lo harías? Para esta gente hacer eso es ser un héroe.”
“If you're inside a system that thinks all of this is fine and rewards you for it, and you do it believing you'll go to heaven, why wouldn't you? For these people, doing that is being a hero.”
Juan reacts to a security-camera video of a suicide bomber walking calmly toward police, and to the original poster's explanation that in some communities the family celebrates the act as heroism and a path to paradise, which is what accounts for the calm. He is explicit that he finds the act terrible and holds to his own golden-rule counterpoint; the takeaway he keeps is not about the act but about conditioning. Behavior that is monstrous from the outside can feel heroic from the inside when the whole system around a person, family included, is built to reward it. Reported faithfully, endorsing nothing, as a hard case in how belief shapes what feels rational.
El inglés que está en todos los idiomas
“El inglés ya ganó mucha fuerza y suele estar en muchos idiomas. Entonces, cuando uno está estudiando algo desde inglés hacia otro idioma, suele reconocer muchas palabras en inglés como si fueran del idioma que estoy practicando. Queda hello, is, you.”
“English has gained so much force that it tends to be in many languages. So when you're studying from English into another language, it keeps flagging English words as if they belonged to the language you're practicing. You end up with hello, is, you.”
A subtle failure in the language-detection backend. The Word Frequency check assumes a word that appears often in a language belongs to it, but English is everyone's second language, so loanwords break the assumption: milkshake is frequent in both English and Portuguese, and a German speaker will drop hello into German freely. The result is that learning from English into another language pollutes detection worst of all, because common English function words get counted as target-language vocabulary. Pairing the deterministic Lingua identifier with the frequency check improves it, but the universal-English case is the residue that keeps leaking through.
Sorprender al músculo, correr contra el tiempo
“Si tú tienes un chat abierto toda la vida, tienes toda la vida para responder. Pero en la vida real, si alguien te pregunta milk or cream, no tienes 5 horas, tienes 2 segundos.”
“If the chat stays open forever, you have forever to answer. But in real life, if someone asks 'milk or cream', you don't have five hours, you have two seconds.”
Julia's argument for why Severo needs variety and a timer. In the gym you surprise the muscle with different movements so it grows, and the video opens with thirty-one push-ups nobody knew they could do; the brain works the same way, so a single card-flip stimulus repeated forever stops teaching. The timer adds the missing pressure: an always-open chat trains you to recognize a word, but recognition is easy, mastery is retrieving it in two seconds under stress, which is the speaking reflex most self-taught learners never build. That gap is why people say they understand a language better than they can speak it.
El campus vacío y el filtro del carro
“Cuando uno entra caminando o en bici necesita pedir permiso, un QR. Cuando uno entra en carro, cero, la seguridad es cero. Se me hace un poco clasista, muy de apariencia. Aunque entiendo que es un filtro sencillo entre persona de bien y persona de bien dudoso.”
“Walking in or on a bike you need permission, a QR code. Coming in by car, nothing, security is zero. It feels a bit classist to me, very appearance-based. Though I get that it's a simple filter between a decent person and a doubtful one.”
The user-testing trip doubles as a portrait of a hollowing institution. Juan, now an alumnus, spent thirty-five minutes stuck at the gate because a guard wouldn't let his partner in without a pre-registered QR, a rule enforced only on those who arrive on foot, never on those in cars. Inside, the campus is beautiful and half-empty: a first-semester class that once took two hundred is down to fifty, and by fourth semester to twenty, while tuition keeps climbing. The gate filter reads to him as a proxy for class, and the emptiness as a place increasingly closed and hierarchical, wasting the campus it's protecting.
Los mitos que sobrevivieron a su causa
“Yo crecí con la mentalidad de que uno no puede dejar el celular conectado en la toma porque se daña. Dejar calentando el carro. Son cosas que en la época hacían sentido, pero hoy ya no. Se vuelven mitos que se propagan y la gente cree.”
“I grew up with the idea that you can't leave the phone plugged in or it breaks. Warming up the car. Things that made sense back then, but not anymore. They turn into myths that spread and people believe.”
A dead laptop battery prompts a small teardown of technical folklore, don't leave it charging, warm up the engine, cycle the first charge to 100% then 0%, rules that were once true and are now superstition. Paired with the flip side: information that democratizes a skill. Fifteen years ago opening a phone meant breaking three to learn; today a YouTube tutorial and modular parts make anyone a repairman. Yesterday's necessity is today's myth; yesterday's expertise is today's tutorial.
Mataron su propia pizza
“El logo casi que era una pizza. ¿Cómo es que quitan la pizza del menú, si eso es lo principal? Yo creo que ellos mismos mataron el producto, porque con cada año que le subían más a la pizza, la gente comenzaba a querer menos y menos, hasta que ya.”
“The logo was practically a pizza. How do you take pizza off the menu when it's the main thing? I think they killed their own product, because every year they raised the price, people wanted it less and less, until it was gone.”
A neighborhood pizzeria, de Nico, whose logo was a pizza, quietly dropped pizza from the menu after years of price hikes strangled demand. Juan reads it as a firm killing its own flagship by pricing it out of reach, a small teardown of the same dynamic that governs Severo's own pricing caution: raise the price on the thing that defines you and you can lose the thing itself.
Empezar en la cadena
“Le recomendé a mi mamá: para tu primer ejercicio, ve a Smartfit, para perder ese miedo de 'no es para mí'. Ya sabes cómo funcionan los equipos, todo estandarizado. Después, cuando ya tengas noción, te pasas al de barrio.”
“I told my mom: for your first time working out, go to Smartfit, to lose that fear of 'this isn't for me'. You learn how the machines work, everything's standardized. Later, once you've got the hang of it, you move to the neighborhood gym.”
Switching to a cheaper neighborhood gym themselves, they name an onboarding principle: the standardized, forgiving, less-intimidating version (a big chain, or Planet Fitness with no loose weights) is where a beginner overcomes the intimidation barrier, and only then are they ready for the cheaper, rougher, harder-to-read option. A product's first-run experience should be the chain gym, not the neighborhood one.
Aprendices pasivos, aprendices serios
“Toda la gente que lo ha probado es más como aprendedores medio pasivos, como la gente que está en Duolingo, que literalmente es muy pasiva. Necesitamos gente que realmente esté aprendiendo algo seriamente, alguien de afuera, que esto no sea su trabajo.”
“Everyone who's tried it is more of a passive learner, like the people on Duolingo, who are very passive. We need people who are actually learning something seriously, someone from outside, for whom this isn't their job.”
The distinction that reframes their testing problem: doing a lesson to feel productive is not the same as sitting down to learn seriously. Their own French practice is a job, so their feedback is the feedback of the motivated-by-obligation. The user who would truly sharpen the product is the outsider who wants to learn for its own sake, and that user is exactly who they don't have yet.
El airfryer no estaba dañado
“Mi papá ya la quería tirar: 'yo abrí esa vaina, no le vi nada raro, está dañado, vamos a tirarlo'. La desarmamos y estaba llena de grasa, como grasa de carro. El switch no se oprimía bien. No estaba dañado: estaba sucio.”
“My dad already wanted to toss it: 'I opened that thing, saw nothing weird, it's broken, let's throw it out.' We took it apart and it was full of grease, like car grease. The switch wouldn't press right. It wasn't broken: it was dirty.”
A father-son repair against the discard reflex. The air fryer 'died', but disassembly revealed a switch clogged with chicharrón grease and a worn lever that no longer pressed the button when the basket closed, fixed with tape to enlarge the lever. The same repair-over-replace ethic as the phone screen: diagnose before you discard, because 'broken' is often just dirty or one worn part.
La carne de los monjes
“Seitán es una carne de gluten inventada por los monjes en China. Casi que la misma proteína que la whey: por cada 30 gramos, 26 de proteína, y tres, casi cuatro veces más barato. Una libra nos valió 11.500.”
“Seitan is a gluten meat invented by monks in China. Almost the same protein as whey: 26 grams of protein per 30, and three, nearly four times cheaper. A pound cost us 11,500.”
Frugal-by-choice, made concrete. Cooking seitan from vital wheat gluten (skipping the wash-the-flour step by buying the gluten directly), the couple finds a vegetarian protein matching whey gram-for-gram at a fraction of the price, though whey wins on completeness (gluten is low in lysine, better paired with legumes). The lesson lands with the chew: they cooked half a pack and still overate, so 'por favor, no hagas todo el paquete'.
Tres meses por no avisar
“Después el man se dio cuenta que lo había arreglado en octubre, y se le había olvidado a la persona avisarle, y a la persona también le había dado pereza escribirle. Tú pagaste por un servicio y en tres meses lo recibes.”
“Then the guy realized he'd fixed it back in October, and he'd forgotten to tell the customer, and the customer had also been too lazy to write. You paid for a service and you get it three months later.”
Sebastián the repair-shop owner, explaining why he wants a CRM for technicians: a phone repaired in October, asked about in February, sat done for three months because neither side pinged the other. The anecdote is the whole argument for a status tracker that sets a customer's expectation, and a quiet field-validation of a real, unglamorous pain.
Una casa que perdona
“Se me cayó el celular, no se me rompió. Se me cayó mi abuelito, no se rompió la pierna. Se me cayó el niño, no se me quebró la cabeza. Si alguien acá en el futuro está viendo esto, por favor, róbese la idea y hágame una casita así bien friendly.”
“The phone falls, it doesn't break. Grandpa falls, no broken leg. The kid falls, no cracked head. If someone in the future is watching this, please, steal the idea and build me a house that's this friendly.”
Prompted by yet another dropped phone, Juan asks why floors and walls are hard, and sketches a product: a cushioned floor and wall material that keeps tile's cleanability but forgives a fall, of glass, of a phone, of a body. He notes the obstacles (porous means dirty) but insists there must be a version, and pairs it with an architecture aside, load-bearing columns hold the house, so the surfaces are free to be gentle. A hobbit house of naturaleza, put on the record for whoever builds it.
Duplicar y agrandar
“Me dijo que me demoraba diez minuticos más, y yo, uy, no, qué pereza. Ahí se me ocurrió la cosa más simple y chambona: duplicar la moneda, agrandarla un poquito por los lados, y así tapé el huequito que quedó sin la imagen.”
“It told me it'd take ten more minutes, and I went, ugh, what a drag. Then the simplest, hackiest thing occurred to me: duplicate the coin, scale it up a bit at the edges, and that covered the little hole left where the image was missing.”
Modeling the game's 3D coin in Blender, guided step by step by ChatGPT (screenshotting each stuck window, 'I'm here, what's next?'), Juan hits a transparent gap in the mesh. Rather than fix it properly, he clones the coin and scales the copy to hide the flaw, a duct-tape solution he cheerfully calls chambona. The tool he half-forgot became usable again only because an LLM narrated the buttons in real time.
La pantalla barata es una estafa
“Si compro una pantalla baratica y después lo vendo, va a ser casi como estafar a la gente. La persona va a decir: ah, listo, se le cae una vez, se rompió, me toca comprarme otra. Entonces por eso compraré la original.”
“If I buy a cheap screen and then sell the phone, it's almost like scamming people. The buyer will say: right, it falls once, it breaks, now I have to buy another. So that's why I'll buy the original.”
Weighing the screen repair, Juan turns a cost decision into an ethics one. A cheap panel would let him resell the phone at a profit, but he knows from experience it breaks on the first drop, so selling it that way is a quiet '171' (Brazilian slang for a con). The original costs more and earns nothing extra on resale, and that's exactly why he'll buy it.
La prueba de que existió
“Hoy en día cualquier persona, en un concierto, para sentir que existió y dar la prueba de que está existiendo, saca el celular. ¿Usted estaba realmente presente ahí? ¿Conoce quién estaba a su izquierda, quién a su derecha? Yo creo que no.”
“Today anyone at a concert, to feel they existed and to give proof they're existing, pulls out the phone. Were you really present there? Do you know who was on your left, who was on your right? I don't think so.”
Part of the cease-to-exist argument: recording the show becomes the substitute for attending it, fifty stories posted as evidence of a presence you never actually had. Juan's twist is that an artist is likelier to truly see, and remember, the one person who isn't holding up a phone. The wish that follows is why he wants a wrist camera, to look at the world through a lens without stepping out of it.
Flutter no es para páginas
“Yo no sé por qué me vino la palabra Flutter, y yo, ay sí, sí, que sirve para adaptar a todas las versiones. Cargaba una página en blanco. I can see nothing. Help me open again. Nada.”
“I don't know why the word Flutter popped into my head, and I went, oh yeah, it adapts to every version. It loaded a blank page. I can see nothing. Help me open again. Nothing.”
Julia, retelling the afternoon she tried to build the Severo landing page and vibe-coded herself into a wall: convinced Flutter was the way to make a page responsive, she ran flutter run over and over and got a blank Chrome tab every time. The bug was conceptual, Flutter compiles apps, not simple web pages, and she admits she'd never have spotted it without Juan glancing at her screen. The lesson she keeps: en la práctica se aprende.
Saber dónde es el límite
“Deberíamos estar para saber dónde es el límite, ¿no?”
“We should be the ones who know where the limit is, shouldn't we?”
Julia, mid-session of poking Severo with progressively spicier prompts (starting from 'how do I say merde') while Juan protests that it weighs on his conscience. Her defense is pure QA doctrine: if your product wraps someone else's model, you'd better map its guardrails before your users do. The probing stayed mild; the principle stayed.
La tercera casa del jefe
“Llegó un momento donde yo pensaba: ¿cómo es posible que mi jefe ya va por su tercera casa mientras que yo todavía sigo arrendando?”
“There came a moment when I thought: how is it possible that my boss is on his third house while I'm still renting?”
An ex-employee's exit video from the Linus Tech Tips drama binge, retold in the diary as the sentence that indicts the standard company model. It lands mid-conversation about their own incubator dream and becomes its negative constraint: whatever the buildings-around-the-world plan turns into, it can't be the machine where a few win and the people who built it watch from a rental.
El oso bebe leche
“Duo te enseña 'el oso bebe leche'; Severo te enseña 'un café fuerte, y rápido, porque estoy de resaca'.”
“Duo teaches you 'the bear drinks milk'; Severo teaches you 'a strong coffee, fast, because I'm hungover'.”
Julia narrating her favorite of the Nano Banana Instagram posts, the one-image pitch for the whole product philosophy: useless textbook sentences versus the sentence you actually need at a counter. The campaign around it stars Severo eating the Duolingo owl, breaking trophies ('no more medals for mediocrity') and congratulating your 200-day streak on behalf of your impressed grandmother while you still freeze when a barista asks milk or cream.
Regionalismos
“Cuando ya estuvieran establecidos los currículos, pienso que sería chévere tener unidades aparte: regionalismos de los países. Expresiones colombianas, mexicanas, puertorriqueñas; portugués de Brasil, de Angola, de Mozambique.”
“Once the curricula are established, I think it would be lovely to have separate units: the countries' regionalisms. Colombian, Mexican, Puerto Rican expressions; Portuguese from Brazil, from Angola, from Mozambique.”
Julia, mid-curriculum-build, sketching the feature no competitor ships: after the universal curriculum covers all 38 languages, add units for how each country actually talks. Filed for a year or two out ('ya es complejo'), but she's the one watching Tapas & Beijos with a Colombian who understands 70% of it, so she knows exactly what the textbooks leave out.
Soy mujer, tengo piernas y salgo sola
“El problema es: yo soy mujer, yo tengo piernas y yo salgo sola.”
“The problem is: I'm a woman, I have legs, and I go out alone.”
Julia's inventory after a seven-minute walk to buy vegetables drew three catcalls, from a car in traffic, from a bike, from a truck that slowed to pace her. The pattern they name on camera: it happens from vehicles that can flee, never on foot, and never when she walks accompanied. The video's closing PSA is Juan's: if you're a man watching this, don't do it, nobody likes it.
La última cartada
“No hay que poner la última cartada ya, cuando las otras cosas no están tan bien. La cosa se va evolucionando; de aquí a cinco años ya va a estar mucho mejor.”
“Don't play your last card now, while the other things aren't that good yet. It keeps evolving; five years from now it will be much better.”
Julia, volunteering to build Severo's image bank by hand after testers kept deflating at emoji exercises. Juan reaches for scale (three hundred images, five hundred); she counters with sequencing: 150 now, because pouring your best effort into one feature while the rest limps is playing the trump card into a losing hand.
Los silencios que no incomodan
“Una buena métrica es: si hay silencios y no se siente incomodidad, es que usted ya está cómodo con la persona.”
“A good metric: if there are silences and no discomfort is felt, you are already at ease with that person.”
End-of-video musing: he notices he and Julia never feel awkward silences and wonders when exactly a relationship crosses that line. The counterexample is close at hand: friends who reach for their phones the moment conversation lapses, doom-scrolling until an idea falls from the sky. Comfort, measured by what you don't need to fill.
¿Quién en 2026?
“A veces reclamas de los actos que hace alguien que está a tu lado.”
“Sometimes you complain about the very behavior of the person right beside you.”
Lying in bed, he scrolls the comments of an old XXXTentacion song and predicts the inevitable 'who's listening in 2026' comment at the top, then launches into a speech about how basic and ephemeral those comments are. A YouTube notification interrupts him: someone replying to Julia. He opens it. Julia's comment, on an old funk song, reads exactly '¿Quién en 2026?'. Her verdict became the seed.
¿Por qué no puedo simplemente hacer click?
“Yo cogía el Google Traductor de la época y traducía cada palabra, cada palabra, porque a mí me gustaba, yo estaba interesada en entender la historia. Y yo siempre pensaba: ¿y por qué no puedo simplemente hacer click?”
“I'd take the Google Translate of that era and translate every word, every single word, because I liked it, I was invested in understanding the story. And I always thought: why can't I just click?”
Julia, on reading manga in English as a kid because the scanlations arrived earlier than the Portuguese ones. The childhood friction became a product spec twenty years later: day one of the French challenge, she asks Severo for a tap-any-word dictionary, and the team realizes the click doubles as telemetry, every tapped word is a word the system now knows you don't know.
Hágalo entender con él mismo
“La mejor forma de combatir la desinformación con la gente que no piensa dos veces es hacer un video con la propia persona que está dudando. Si es corintiano, póngale la camisa del Palmeiras, para que entienda que es falso.”
“The best way to fight disinformation with people who don't think twice is to make a video of the very person who's doubting. If he's a Corinthians fan, put a Palmeiras shirt on him, so he understands it's fake.”
Julia retelling the top comment under a viral AI-generated video of Lula fighting Bolsonaro that plenty of viewers took as real. Arguments don't inoculate someone who wants to believe; a deepfake of themselves does, because the impossible thing is now wearing their own face. The pedagogy is the same one Severo bets on: people don't learn from being told, they learn from being put inside the example.
La única función del tablero
“Uno puede trabajar igual en un whiteboard en el computador, pero uno se desconcentra y comienza a hacer otras cosas. El tablero, la única función que tiene es estar ahí y poder escribir uno encima, y eso es lo que uno hace y lo cumple.”
“You could do the same work on a whiteboard app on the computer, but you get distracted and start doing other things. The board's only function is to be there and let you write on it, and that's what you do, and it delivers.”
Said while hanging a physical whiteboard on the wall with a single nail, next to the NFT-days painting. It's the bloquito philosophy extended to furniture: a tool that can only do one thing cannot betray you into doing another. The computer offers infinite surfaces and therefore infinite exits; the board on the wall offers exactly one, which is why it gets used.
No somos Mr. Beast
“Hay que ser humildes: nuestra realidad es que no somos Mr. Beast. Yo siento que eso es algo muy clave en cualquier cosa que uno hace, que la expectativa y la realidad estén lo más cercano posible.”
“We have to be humble: our reality is that we're not Mr. Beast. I feel that's key in anything you do, that expectation and reality stay as close together as possible.”
Announcing the channel's new thumbnail style, live in this very video. The colorful Mr. Beast-style miniatures promised something the videos never were; the reality is two people in front of a camera talking through their day, closer to a podcast. Asked for alternatives, Gemini suggested CCTV, collage, VHS grain, 'the complete opposite of a Mr. Beast thumbnail,' and he reports the verdict as a demotion he accepted: 'bajé de mi pedestal.' The supporting data was already in the analytics: the diary's most-viewed videos are the organic ones. Same principle he applies to over-hyped Airbnbs: inflate expectation past reality and the visitor leaves angry.
No significa nada para mi futuro
“Me gustaría acreditar que el que no haya conseguido logros muy relevantes en el pasado no significa nada para mi futuro. Eso es lo que yo quiero pensar, y voy a esforzarme por hacerlo real.”
“I'd like to believe that not having achieved anything very notable in the past means nothing for my future. That's what I choose to think, and I'm going to work to make it real.”
The end of the prodigy-myth debate sparked by the DeepMind documentary: Demis Hassabis was a world-class chess kid at four, and Sam Altman's heuristic says past achievements predict future ones. He inventories his own record honestly (never competed at university, wanted the degree and out, and a recent interview died on the question 'what did you achieve?'), then refuses the heuristic's verdict. It isn't a claim about the evidence; it's a declaration about which belief he intends to make true.
Descubrí que no estoy sola
“En esta comunidad descubrí que yo no estoy sola.”
“In this community I discovered I'm not alone.”
Julia, on finding r/fuckcilantro, the subreddit for people whose gene mutation makes cilantro taste like soap. The thread they scroll together is an epistemology lesson disguised as a food fight: someone with the soap gene asks what cilantro actually tastes like, top answers offer 'fresh and bright' (which are not flavors), and the closest anyone gets is 'lemony parsley.' He compares it to explaining color to the colorblind. But the line that survives is hers, and it's the entire value proposition of a niche community stated in seven words: the product is the discovery that you're not the only one.
Feliz y al mismo tiempo infeliz
“En retrospectiva uno lo ve como un tiempo bonito, pero yo me acuerdo que en el momento yo me sentía una persona un poco infeliz. O sea, feliz y al mismo tiempo infeliz.”
“In retrospect you see it as a beautiful time, but I remember that in the moment I felt like a somewhat unhappy person. Happy and unhappy at the same time.”
Remembering the digital-nomad month in Teresópolis: traveling while working sounded like the dream, but every new town meant a new gym, a new kitchen, higher prices, no savings left over, and the feeling of not progressing. The memory surfaces because today felt the same, a day eaten by dishes and meals, and it ends in a concrete resolution: revive last year's work timer, now set to seven daily hours, with Julia signing up for five. Routine, in this telling, is not the enemy of the adventure; it's what the adventure was missing.
La cara y la cicatriz
“Hay un dicho en portugués: quien mira la cara no mira la cicatriz. Uno mira, uy, esta gente ahí viviendo con tanta tierra, pero mire por detrás: cicatrices.”
“There's a saying in Portuguese: whoever looks at the face doesn't see the scar. You look and think, wow, these people living with all that land, but look behind it: scars.”
Julia's coda to the 74-year-old landowner's story: a bank career erased by a run on the banks, seven lean years of selling cakes and failed farming, and only then the mountain finca that visitors now envy. The proverb is her answer to the survivor-bias reading of every comfortable elder: people always assume the things were gotten easily, and the scars are exactly what the face doesn't show.
El océano morado
“Hay muchos aplicativos malos, muchos. Y la gente paga. Entonces, a pesar de que es un océano rojo, si se hace un filtro, el océano es menor de lo que parece; está más para un morado que un rojo. Todavía no está tan saturado de los buenos buenos, de los que uno diría: wow, esto me gustaría.”
“There are a lot of bad apps out there, a lot. And people pay. So even though it's a red ocean, if you apply a filter, the ocean is smaller than it looks; it's closer to purple than to red. It still isn't that saturated with the genuinely good ones, the ones that would make you say: wow, I'd love this.”
Julia's closing read on the 25-app gauntlet, delivered right before the passive-learning critique. Language learning is the textbook red ocean, Duolingo and a hundred clones deep, and the conventional advice is to stay out. Her filter inverts it: once you subtract the apps that are more-of-the-same, the paywalls-first apps, and the ones that record your voice and grade nothing, the competitive water dilutes to purple. The market's willingness to pay for bad products becomes the evidence that a good one has room.
Pum, premium
“Tú te metes en la aplicación, descargas, primer clic y pum: popup del premium. ¿Quieres salir? Otro. Comienzas un ejercicio, uno; terminas el ejercicio, otro. Son como diez. Y cuando finalmente dices, bueno, vamos a empezar a jugar: pum, premium, no se puede usar.”
“You get into the app, download it, first tap and boom: premium popup. Want to exit? Another one. Start an exercise, one; finish the exercise, another. It's like ten of them. And when you finally say, okay, let's actually play: boom, premium, can't use it.”
Day one of the competitor gauntlet, a full page of language-learning apps installed and tested one by one until it caused headaches, and this duet between the two of them captures the dominant genre finding: paywalls stacked so aggressively that the product never gets to make its case. They milked the free trials with the cancel-the-card trick, and the early scoreboard splits between 'Severo es 10 veces mejor que esto' and the occasional humbling 'esta sí es mejorcita.' The full analysis is promised for the next video.
Spotify no hace canciones
“Yo veo un futuro en donde los manes se vuelvan su propia disquera: con la misma suscripción que usted paga, nosotros nos encargamos de compartir en todas las plataformas las canciones que usted cree. Sería simplificar toda la creación al máximo. Porque Spotify no hace canciones; ninguna plataforma.”
“I see a future where those guys become their own label: with the same subscription you already pay, we take care of publishing the songs you create to every platform. It would simplify creation to the maximum. Because Spotify doesn't make songs; no platform does.”
Fresh from running his father's Suno-made song through a distributor's gauntlet of upsells, he spots the unbundled seam: generation tools make music but don't distribute it, and platforms distribute music but don't make it. Whoever does both under one subscription collapses the whole pipeline. Said as a prediction about the AI-music companies, filed here as a product thesis about where value pools when creation gets cheap.
Me gusta que me reten
“Yo le dije que realmente la podemos hacer rentable dentro de poco tiempo. Él dice que no cree, que eso posiblemente se demore como un año. Y es chévere: a mí me gusta que me reten.”
“I told him we can really make it profitable in a short time. He says he doesn't believe it, that it'll probably take about a year. And that's great: I like being challenged.”
Inside the meeting that closed the six-month investment, the founder's optimism met the investor's realism head-on, and instead of deflating him it armed him. The investor's skepticism came bundled with structure, roles, weekly meetings, a scaling horizon, which is what made the doubt feel like coaching rather than dismissal. A bet against your timeline, placed by someone who just funded you anyway, is the friendliest possible provocation.
La realidad no es color de rosa
“Me gustan muchas veces esas historias que son duras porque se sienten muy reales. Es como que le dicen a uno: la realidad no es solamente color de rosa como usted puede estarla viviendo; esto también puede ser la realidad, o incluso es la realidad de mucha gente.”
“I often like those hard stories because they feel very real. It's like they tell you: reality isn't only rose-colored the way you may be living it; this can also be reality, or it already is the reality of a lot of people.”
The Kobo can't zoom infographic text at night, so he trawled his library and opened a book of unknown provenance whose title spoke to him: El hombre en busca de sentido, an Auschwitz survivor's account. One preface in, he's already collecting lines, Nietzsche's he-who-has-a-why, life as a search for meaning rather than Freud's pleasure or Adler's power, success as a thing that, like happiness, cannot be pursued. The bridge he draws lands on the present: the oppressed of the camps have counterparts now, and Julia closes it, remember so the past doesn't repeat.
Todos quieren ser el James
“Él mismo me decía que es más difícil que lo fichen a uno como delantero, porque precisamente hay muchos delanteros; todos quieren ser el James, todos quieren ser la estrella. Y por eso le gusta el centro del campo.”
“He told me himself that it's harder to get signed as a striker, precisely because there are so many strikers; everyone wants to be James, everyone wants to be the star. And that's why he likes central midfield.”
The fourteen-year-old footballer already reasons in supply and demand: scouts from clubs like Millonarios come watch for traits like sacrifice, his example being the teammate who took a goalpost to the shin saving a ball, and the striker position is oversubscribed because everyone wants to score the goal. So he plays midfield, where the competition is thinner and the pass still runs through him. Positioning against the crowd, learned before the growth spurt.
Free Severo
“Ahorita Severito está encerrado en la Google Play, así como en cadena de rejas, y lo tenemos que liberar. Hashtag Free Severo.”
“Right now little Severo is locked up in Google Play, behind bars and chains, and we have to set him free. Hashtag Free Severo.”
Day one of the second 14-day test cycle, and the recruiting drive is on: a post in the Vibe Coding Anónimo group brought four volunteer testers, with friends and Julia's friends next on the list toward the twelve Google demands. The stakes as he frames them: an app that isn't publicly available doesn't get killed, 'se muere solito', it dies alone. Julia's contribution is the campaign art direction: post Severo behind bars.
Una navaja suiza de motores
“Yo me puse a pensar: ¿por qué no existe como un dispositivo, como una navaja suiza, para cosas que necesiten el motor de licuadora?”
“I got to thinking: why doesn't there exist a device, like a Swiss Army knife, for things that need a blender's motor?”
The hair-dryer repair spawns a product idea: dryer, vacuum, blender, mixer, food processor, all wrappers around the same motor. Julia immediately finds the partial precedent, immersion blenders with swappable heads, and Lego's universal motors. His own counterargument is why the idea stays a seed: specialization is the reason their ten-year-old blender still works, and a motor with interchangeable everything might work worse and become dangerous. The itch survives the objection: one motor, many heads.
El hombre de tres metros
“Lo loco es eso: a primera vista, cada vez es mucho más difícil identificar qué es IA y qué es lo que no.”
“That's the crazy part: at first glance, it keeps getting much harder to tell what's AI and what isn't.”
A viral home-renovation video fooled him because his old heuristic, AI clips run ten or twelve seconds with constant cuts, met a single continuous take. Julia's uncanny-valley instinct won on different evidence: no human cleans the top half of a wall and wanders off, concrete appeared where water was sprayed, and the worker who looked small on the ladder stood nearly three meters tall at the bottom of it. Detection is becoming a checklist of physics and workflow errors, and the checklist keeps shrinking.
No hay otra manera
“Hablando con la familia y reflexionando y retomando los puntos principales del por qué estamos haciendo esto, fue como que: venga, esto es lo que usted quiere, usted lo tiene que hacer, no hay otra manera.”
“Talking with the family and reflecting and going back over the main reasons why we're doing this, it was like: come on, this is what you want, you have to do it, there is no other way.”
December of year one was the low point of the motivation rollercoaster: four euphoric founding months, then the money running out, then asking why am I even doing this. The repair was archaeological, re-deriving the original reasons for quitting the job, working from anywhere without timezone chains and studying AI architectures deeply, until the conclusion reassembled itself. Some conviction isn't found; it's re-derived from first principles when it breaks.
Nunca pasa nada
“La persona que me estaba atendiendo era venezolana y yo le preguntaba qué pensaba de lo de Trump y la invasión, y el man básicamente decía: 'Nunca pasa nada, nunca pasa nada, y no va a pasar nada.' Y mire: ese fue el 31, y tres días después, pumba, tómala.”
“The person cutting my hair was Venezuelan and I asked him what he thought about the Trump thing and the invasion, and the guy basically said: 'Nothing ever happens, nothing ever happens, and nothing is going to happen.' And look: that was the 31st, and three days later, boom, there you go.”
A barbershop fade on New Year's Eve, a Venezuelan barber's weathered fatalism, and history contradicting him within seventy-two hours: on their telling, Maduro captured by the United States. The people closest to a crisis are often the least able to believe it will ever break.
Curso para tener un perrito
“Hay países, yo creo que Finlandia, Noruega, en que tú para tener un perrito tienes que completar algunas horas de curso de entrenamiento… La cosa es que no hay eso con los padres. Los padres no tienen un manual de instrucción.”
“There are countries, I think Finland, Norway, where to have a puppy you have to complete some hours of training course… The thing is, that doesn't exist for parents. Parents don't come with an instruction manual.”
Mid-conversation about relatives raised between two households, hero-house and villain-house, and the double personality Julia theorizes it breeds, she lands the asymmetry: some societies require certified training to adopt a dog, and none to receive a human being who depends on you 24/7 to eat, bathe, and learn. The species licenses the smaller responsibility.
Tu vida tiene un fin
“No sea tan egoísta al punto de crear una marca que te enorgullece y todo eso, pero tu vida tiene un fin… ella no entrenó a nadie, no tenía un aprendiz. Entonces cuando ella murió, la marca pasó por cuatro o cinco manos de gente que cambió mucho el estilo.”
“Don't be so selfish that you build a brand you're proud of and all that, but your life has an end… she trained no one, she had no apprentice. So when she died, the brand passed through four or five hands, people who changed the style completely.”
Julia's takeaway from the Chanel story, aimed at every founder who is the product: succession is part of the design. The house that dressed working women became a luxury label the moment its author stopped breathing, because nothing of her method lived in anyone else's hands.
Los espacios entre primos
“Me puse a entrenar una red neuronal para predecir cuál es el espacio que va a tener entre un primo y otro… conseguí como un 50% de accuracy en el primer guess, con el tercero ya era como un 70%, y con el décimo ya era como el 97%.”
“I started training a neural network to predict the gap between one prime and the next… I got about 50% accuracy on the first guess, by the third it was around 70%, and by the tenth it was about 97%.”
A sick day in Bucaramanga, and the idle hands train a network on the gaps between prime numbers, then joke about 'proving' the Riemann hypothesis with Antigravity. Nothing novel, he says, and that's the point of the seed: the research reflex survives standby, vacations, and the flu.
Tres semanas, cincuenta dólares
“Ya llevo como casi tres semanas intentando tener la platica de unas inversiones de Etoro en mi cuenta Bancolombia… El momento en que me di cuenta que era PayPal, yo ya sabía que iba a dar mal. PayPal, ya tengo mi experiencia con PayPal, y es una porquería.”
“I've now spent almost three weeks trying to get the money from some Etoro investments into my Bancolombia account… The moment I realized it was PayPal, I already knew it would go badly. PayPal, I've had my experience with PayPal, and it's garbage.”
Fifty dollars from selling Google and TSMC scraps: two weeks of Etoro support demanding different screenshots (he rated them one star), the discovery that a business PayPal can never become personal again, a brand-new account, and now PayPal's first-withdrawal ritual, a verification phone call within five business days. Field research for Reisi, invoiced in patience.
Uber más barato de noche
“Acá en Bucaramanga parece que de noche los Ubers, o el servicio de transporte, es más barato que de tarde… puede ser que por las noches, como hace más fresquito y hay menos tráfico, a la gente le gusta trabajar a esa hora. Mucha oferta y poca demanda.”
“Here in Bucaramanga it seems that at night the Ubers, or ride services, are cheaper than in the afternoon… it may be that at night, since it's cooler and there's less traffic, people like working that hour. Lots of supply and little demand.”
The 12,000-peso ride out costs 7,000 coming back, and he can't leave the anomaly alone: heat and traffic as labor-supply variables in a tropical city. A benchmark video ends with field microeconomics, priced by the same marketplace algorithm he spends his days thinking about.
Yo no he dicho ni pío
“Habíamos imprimido unas camisas verdes con unas frases de mi nona, mi difunta abuela… acá dice 'Yo no he dicho ni pío', de mamá Lola. Y pues básicamente toda la familia se la compró y se la puso.”
“We had printed some green shirts with phrases from my nona, my late grandmother… this one says 'I haven't said a peep', from mamá Lola. And basically the whole family bought one and put it on.”
Christmas Eve in Bucaramanga: thirty relatives in matching green shirts, each printed with a classic saying of mamá Lola's, some with her face, kids swarming like Tasmanian devils underneath. Grief converted into wearable memory, and the family photo doubles as her best quotes page.
Carros en la calle
“Eso también es una indicación de que es un barrio bien seguro, el hecho de que hay carros en la calle. O sea, en Colombia, ¿en dónde se ve un carro en la calle? Ya es símbolo de peligro.”
“That's also an indication that it's a really safe neighborhood, the fact that there are cars on the street. I mean, in Colombia, where do you ever see a car parked on the street? That's already a symbol of danger.”
Walking down from the Bucaramanga mountain at dawn, Julia notices cars left out overnight and reads them instantly: an urban trust index no statistics bureau publishes. Where theft is priced into daily life, the street empties; where it isn't, the cars sleep outside. The best security metric is what people are willing to leave unguarded.
Chisme de la Biblia
“Julia se va a dormir y se pone a hablar sobre la Biblia en ChatGPT, y Julia ni es creyente ni nada de eso… es como fan girl, tipo esos fans de Star Wars, pero de la Biblia. Encontró a alguien para hacer chisme de la Biblia.”
“Julia goes to bed and starts talking about the Bible with ChatGPT, and Julia isn't even a believer or anything… she's like a fangirl, like those Star Wars fans, but of the Bible. She found someone to gossip about the Bible with.”
A week of novenas has Julia deep in scripture lore, and her nightly ritual is theological gossip with a chatbot: not devotion, fandom. The couple that debates whether AI erodes intuition also demonstrates its warmest use case, an infinitely patient conversation partner for whatever obsession the week brings.
Los bolardos del Metrolínea
“El Metrolínea se acabó y esos bolarditos amarillitos no los han quitado. Quién sabe por qué.”
“The Metrolínea shut down and those little yellow bollards, they haven't removed them. Who knows why.”
On the way to the novena a motorcyclist crashes almost in front of the car: he tried to merge into the lane of Bucaramanga's dead BRT system and clipped one of the bollards still guarding a bus that no longer exists. A self-declared paramedic contributes only tips (no water, let his movements be his own) while the ambulance takes its time. Infrastructure outlives its purpose and keeps collecting casualties.
Digitalizar la plata
“Yo tenía plata en efectivo, pero tenía pendiente, y eso sí se me pasó, meter plata a la cuenta… digitalizar la plata. Porque con la plata en la cuenta uno puede comprar pasajes en internet.”
“I had cash, but I had it pending, and this one did slip past me, putting money into the account… digitizing the money. Because with money in the account you can buy tickets online.”
The founders of a payments startup get stranded by undigitized cash: online tickets sell out while their pesos sit on paper, the counter price climbs from 130,000 to 143,000, and the 1:30 a.m. Copetrán is the only bus left. Two hours on the terminal floor become the office where the financial simulation and the padrino rejection get written. The product thesis, lived from the user's side of the glass.
Una vida para darle sentido
“Crear una vida sin padre, y más, crear una vida como para encontrarle sentido a la tuya… termina siendo realmente como un poco tóxico.”
“Creating a life with no father, and worse, creating a life to give meaning to your own… it really ends up being a little toxic.”
A Slowly letter from a divorced woman in China ends with a photo: her seven-month-old son, conceived by IVF from a donor chosen for his nice face, because after the divorce she felt she had lost her reasons to live. Julia's verdict is sharper still: have a child out of fear of being alone and you condemn him in advance to stay forever at your side. The pen-pal app keeps delivering ethics seminars.
Actividad inusual
“El correo que me llega ayer es como que: detectamos actividad inusual. Cambiaste tu número de teléfono y cambiaste el idioma de tu cuenta. Tienes que completar esta verificación para que podamos validar que eres tú.”
“The email I get yesterday is like: we detected unusual activity. You changed your phone number and you changed your account's language. You have to complete this verification so we can validate that it's you.”
The Etoro exit gets worse: the account was opened in Brazil, so the SMS code goes to a dead number; fixing that plus switching the app to English (to follow tutorials) reads as fraud. The remedy is a photo of a cédula where he is 18 with a baby face, a head-turning video reciting numbers, and up to three days of manual review, while the withdrawal races the bus to Bucaramanga.
La única opción es PayPal
“Cuando le doy sacar los fondos, solamente hay una opción y es la peor de todas: PayPal… un 3% por convertir, más cinco dólares de Etoro. Son cositas que van quitándole plata a uno porque sí.”
“When I hit withdraw funds, there's exactly one option and it's the worst of all: PayPal… 3% to convert, plus Etoro's five dollars. Little things that just keep taking your money because they can.”
Closing winning positions to fund the family Christmas trip to Bucaramanga, he discovers Colombia's Etoro exit is PayPal-only, one-star reviews from compatriots agree, with a 3% currency spread, a five-dollar fee, and up to eight days of latency against a bus that leaves in three. Money that enters by Visa in seconds leaves through a toll road. The couple building a payments app takes field notes on their own pain.
El chip relajado
“Un año en Colombia no me hizo bien a mi español. Porque cuando estoy en Brasil yo hablo bien: cuando tengo que cambiar el chip de portugués a español, estoy más consciente de cómo pronuncio.”
“A year in Colombia didn't do my Spanish any good. Because when I'm in Brazil I speak well: when I have to switch the chip from Portuguese to Spanish, I'm more conscious of how I pronounce.”
The paradox surfaces after a Colombian film about campo children defeats her: Julia's Spanish was clearer, Mexican-accented even, before she moved to Colombia. Living 99% in Portuguese at home, the language switch relaxed, and with it the articulation; his mother now watches her talk with a face that says 'what language is this.' The couple's diagnosis, useful to two people building a language tutor: effortful code-switching forces the consciousness that fluency quietly turns off.
Ochocientos reactores
“Necesitaríamos alrededor de 800 reactores nucleares para cubrir ese consumo total de manera continua. — Pero no está tan grande… o sea, menos de mil para todo un continente.”
“We would need around 800 nuclear reactors to cover that total consumption continuously. — But that's not so big… I mean, fewer than a thousand for an entire continent.”
A video of Chinese mountains blanketed in solar panels, dystopian at first sight, softened by a comment noting the region was near-desert, sends them into a voice-mode interrogation about nuclear energy: France at 65%, the whole Americas needing roughly 800 one-gigawatt reactors for 100% nuclear, a number that shocks them by being small. Julia's contribution to the science: steering the AI until it names Brazil's nuclear program, and following up with '¿y quién inventó el avión?'
El rival que era golpe
“Nosotros sí tenemos muy claro que la confianza es clave para cualquier tipo de negocio. Tenemos que sacar algo y sacarlo bien, dar un buen servicio… en ese lado también vamos a innovar.”
“We're very clear that trust is the key to any business. We have to ship something and ship it well, give good service… that's another front where we'll innovate.”
Julia's Instagram tech-trends guy surfaces Maggi, a Brazilian service paying bills and transfers from inside WhatsApp, part of what Reisi wants to be. The excitement lasts until the comments: 'es golpe,' fraud reports, money in and never out, plus a cryptocurrency bolted on. The double lesson they extract: the chat-that-executes concept has proven demand, and a market scarred by scams pays a premium for the one thing scams can't fake.
El gato de League of Legends
“Lo vi, me pareció bonito y yo dije: listo… Y ese gato yo lo apreté fuerte para que no se me fuera.”
“I saw him, thought he was cute, and said: done… And I held that cat tight so he wouldn't get away.”
Niel's origin story, told as the first big decision his family respected, at 14: an adoption post in a League of Legends Colombia group, a meetup arranged at Portal Norte, his brother bailing the morning of ('desapareció como el Avatar'), and his father, who had declared 'usted no me va a traer ningún animal a esta casa,' driving him anyway rather than let him ride to Bogotá alone. The handoff: the girl passed the kitten over the TransMilenio turnstile to avoid paying a second fare.
La llamada sin voz
“Nunca escucho a la persona y la persona tampoco me escucha a mí… Es como la herramienta perfecta para la persona introvertida.”
“I never hear the person and the person never hears me… It's like the perfect tool for the introverted person.”
Julia's find, tested live between their phones: the assistant that answers unknown calls and converts them to a text chat, the caller talking to a robot while you read and pick reply chips. Her original motive is defensive, telemarketers and voice-cloning scams can't sample a voice you never use, and his is social: it deletes the guilt of hanging up on the Movistar guy mid-greeting.
El hijab en el avatar
“Tú tienes la habilidad de expresarte como quieras en esta aplicación; más sin embargo, por como naciste, por como te educaron, tú sientes que eso hace parte de tu identidad, entonces te lo pones en un perfil virtual.”
“You have the ability to express yourself however you want in this app; and yet, because of how you were born, how you were raised, you feel it's part of your identity, so you put it on a virtual profile.”
His pen-pal correspondents on Slowly, women from Indonesia, dress their avatars in hijab inside an app with no dress code at all. It lands mid-debate with Julia about the birthplace lottery, souls dropped at random like in Pixar's Soul, and whether anyone can judge a culture from outside it. His boundary for the whole question: 'mi libertad llega hasta donde empieza la tuya.'
Automático
“La persona no termina estando el cien por ciento ahí con uno. Es como automático: hay un pequeño silencio y la reacción común es agarrar el teléfono y ponerse a hacer doomscrolling.”
“The person never ends up being one hundred percent there with you. It's automatic: there's a small silence and the common reaction is to grab the phone and start doomscrolling.”
Friends visit the house, and every pause in conversation triggers the same reflex in both halves of the couple: phones out, stories, feeds. He catches his own version, the pull toward the computer to keep working, and resists it to keep drawing them out. The frame around the observation: Australia's ban on social media for under-16s taking effect December 10, which they applaud without hesitation, 'niño, es por tu bien,' and his hypothesis connecting the attention-deficit surge to the machines that trained it.
La pizza que no era
“Yo siento que siempre que uno está así, como mal vestido, por así decirlo, la gente comienza a juzgar mucho… Tenía tanto ganas de queso azul que me vendieron esa pizza, y ya después caí en cuenta: yo soy vegetariano.”
“I feel like whenever you show up badly dressed, so to speak, people start judging hard… I wanted blue cheese so badly they sold me that pizza, and only afterwards it hit me: I'm vegetarian.”
Gym clothes, two bicycles, an Italian restaurant with three waiters standing watch over the table like the couple might bolt. Under the surveillance pressure he lets the waiter upsell him a prize-winning pizza, remembers his vegetarianism minutes later, learns the sauce itself is made with anchovies, cancels in front of fifteen onlookers, and lands on the cheapest spaghetti with a blue-cheese add-on. His theory stands: around Bogotá, appearances buy your level of service.
Los huevos en el chat
“Es que esto es un chat: usted no debería tomarlo como su herramienta principal de trabajo… No pongan todos los huevos en una misma canasta; cuando un chat ya queda muy largo, expórtenlo, guárdenlo en algún lado.”
“This is a chat: you shouldn't treat it as your main work tool… Don't put all your eggs in one basket; when a chat gets very long, export it, save it somewhere.”
A Reddit user lost 99% of a legal project, ninety-plus files deep in one Gemini conversation, and the top comment was merciless: Gemini is not a storage platform. His own hygiene: AI Studio branches as accidental backups, Weights and Biases checkpoints for training runs, GitHub at every phase end. And the confessed gap that worries him: some 300 GB of this channel's video masters exist only on YouTube's servers, guarded by nothing but YouTube's reputation.
El corresponsal que cobraba
“Los corresponsales bancarios tienen prohibido cobrarle una tasa al cliente… De nada sirve quejarse sin hacer nada, entonces: vamos a reportar a este man.”
“Banking correspondents are prohibited from charging the customer a fee… Complaining without doing anything is useless, so: let's report this guy.”
The droguería correspondent who charged 500 pesos on a holiday now wants 1,000 for a 400,000-peso deposit, pleading that Bancolombia doesn't pay his electric bill. He walks out, researches the rules, can't even find the shop on Bancolombia's correspondent map, and files the complaint through the full jungle: a WhatsApp chatbot, a 20-minute call, one alarming request for his ATM PIN, two transfers, one radicado, ten business days. The scaling argument for caring about 1,000 pesos: imagine Nequi charging that per transfer.
Cirugía de hormigas
“Las hormigas se hacen cirugía entre ellas, incluso hacen amputaciones, y supuestamente mejora muchísimo su probabilidad de supervivencia.”
“Ants perform surgery on each other, even amputations, and supposedly it improves their survival odds enormously.”
A study circulating on Reddit: a wounded leg gets treated, or when it's too far gone, bitten clean off, and either intervention raises survival dramatically, reportedly the first documented surgery in a non-human species. Julia's taxonomy: file it next to the macaques cracking coconuts with tools. His open question: who else does this and hasn't been caught yet, maybe the bees.
¿No me puedo electrocutar?
“Si hubiera sabido que estaba este Gemini así, yo creo que lo hubiera hecho. Es como que: venga, dígame cómo. Y yo le hubiera preguntado: bueno, ¿y no me puedo electrocutar? No, no, tranquilo.”
“If I'd known this Gemini existed like this, I think I would have done it. Like: come on, tell me how. And I'd have asked it: okay, and I can't get electrocuted, right? No, no, relax.”
A demo of Gemini Live guiding an oil change through the camera, pointing at the actual drain plug, dictating torque so nothing strips. His counterfactual: the day the car alarm wouldn't die and disconnecting the battery felt too unknowable, he waited for someone else instead. The economics land on his own laptop: the shop charges 100,000 pesos for a battery swap, 'lo haría solito.' AI as a transfer of nerve, not just knowledge.
El mercado de pescado
“When you are in a fish market too long, one will get used to the stink… Cuando tú estás acostumbrado a seguir órdenes toda tu vida, a pedir permiso para hacer cualquier cosa, se te olvida que ya no tienes que pedirle permiso a nadie.”
“When you are in a fish market too long, one will get used to the stink… When you've spent your whole life following orders, asking permission for everything, you forget that you no longer have to ask anyone's permission.”
A half-remembered proverb applied three ways: the normalized fear of street robbery, the truck exhaust nobody in Colombia registers anymore, and the deepest one, the permission reflex, school, then university, then bosses, that survives into entrepreneurship long after the last authority figure has left the room.
Aprovechar antes
“Yo en mi familia estoy un poco acostumbrada con la muerte. Tuve al menos tres muertes importantes en la familia, y eso torna a uno que mira la vida un poquito diferente: en vez de lamentarse, uno empieza a vivir las cosas, a aprovechar antes.”
“In my family I'm somewhat used to death. I've had at least three important deaths in the family, and that turns you into someone who looks at life a little differently: instead of grieving what's gone, you start living things, making the most of them beforehand.”
Julia's frame on the night Thor dies, and the reason she pushed for the two extra months in the first place: when father and son came back from the vet ready for the injection, she argued for responsibility, therapy, feeding, time. Her verdict now: Torito got the best days he could have had, and the goodbye was already paid for in advance.
Figma muere lentamente
“Hay que competir con Google, y yo no estoy dispuesto a pagar por Figma… El caso es que Figma está muriendo lentamente.”
“You have to compete with Google, and I'm not willing to pay for Figma… The fact is Figma is dying slowly.”
Julia builds the Reisi mockups in Stitch because 'Figma ya está en el pasado.' The chart on screen: IPO in August around $115 a share, roughly 70% of the value gone by December. Their diagnosis from the ground: Nano Banana, Stitch, and image models ate the mockup, the one job they used Figma for, and the AI-integration play means racing Google with a paid product against free ones.
La ciudad con cáncer
“Vuelve al tema de cómo tú puedes vivir una vida normal y después de unos años finalmente darte cuenta de que uno está paila, por alguna cosa que haya pasado. Realmente no se sabe qué es lo que pasó.”
“It comes back to the theme of how you can live a normal life and only years later finally realize you're done for, because of something that happened. Nobody really knows what it was.”
A deleted Reddit post claimed alumni of a university in Roanoke, USA, showed something like fifteen times the expected cancer rate; he flags the tracking problems himself, alumni scatter worldwide, but the comments were the data: locals reporting mothers and neighbors with breast cancer traced to childhoods there, four women sick at once in one social circle, 'algo está mal con esa ciudad.' The university investigated and found nothing. His takeaway is the invisible-harm theme: a company dirties the water or the air, and the damage is outside your senses until it isn't.
Un mensaje en el tiempo
“Es como que la información, siendo asíncrona, me haya llegado, y ese sentimiento, como un mensaje en el tiempo, así como un encapsulado.”
“It's as if the information, being asynchronous, arrived for me, and that feeling, like a message across time, like something sealed in a capsule.”
His riff on the beauty of asynchronous information: a five-year-old discovers a Michael Jackson song and only later learns he died, and the grief lands fresh, decades late, making the experience unrepeatably personal. The house example is Ayrton Senna: Julia, not yet born when he died, learned him through other people's memories and the fifty Senna films Juan Pablo assigned her, and the jolt of energy arrived intact. You don't need to know everything the moment it happens.
Dejarlo solito
“Es como interesante: cuanto menos información, mejor. Si uno quiere algo de creatividad, simplemente uno tiene que poner la idea y dejarlo solito.”
“It's interesting: the less information, the better. If you want something creative, you just have to state the idea and leave it alone.”
Making the Play Store feature graphic for Severo. The first casual prompt, eight screenshots and 'make it nice', produced the design Julia and he both loved. Then he asked Gemini for ideas first, and the detailed briefs ('lion face at 70% of frame') produced a row of generic lions. Dropping back to near-empty prompts restored the creativity. The graphic still needs one fix: all the example text came out in German.
Los bancos aburridos
“Realmente es lo más loco que he visto, y uno ve esto y queda como que: los bancos de mi país son tan aburridos.”
“It's honestly the craziest thing I've seen, and you look at it and go: the banks in my country are so boring.”
Julia's design research for the Flypay identity, hunting the tone between trustworthy and alive. The two poles on screen: Australia's Up Bank, hippie triangles playing rock-paper-scissors and draggable coins, the maximum extreme; and South Korea's KakaoBank, clean white with choosable rabbit mascots, lovely but reads childish for Colombia. Her target: a middle ground, professional enough that nobody fears for their money, different enough that it doesn't wear a suit. His market note: maybe a guacamaya.
El puestico de piscina
“Una acción tan infantil como esta está destruyendo valor, y ahí está una clara analogía de cómo se destruye valor. ¿Usted qué ganó? Un puestico ahí de piscina.”
“An action as childish as this one is destroying value, and right there is a clear analogy of how value gets destroyed. What did you win? A little poolside seat.”
The working theory of the dead phone: at the pool, a stranger wanted his parents' reserved chairs and allegedly poured water on the phone out of spite. The repair shop pronounces the display unrecoverable. He runs the ledger of one petty act: a new screen, days of downtime, his own week without a phone, and mirrors it against their standing definition of creating value, anything you make that serves someone else, even a candy that makes a kid happy.
El clásico ¿está bien?
“Ya nos íbamos a ir, y después fue como que: ¿no estamos siendo un poquito inhumanos? ¿Cómo nos vamos a ir así como si nada? Y nos quedamos ahí, de eso de que uno no sabe qué hacer.”
“We were about to leave, and then it was like: aren't we being a little inhuman? How do we just walk away like nothing happened? And we stood there, in that state where you don't know what to do.”
Two motorcycles collide crossing to the pizzeria, one ends vertical against a parked car. Ten minutes of bystander fog: the reflexive '¿está bien?', the stranger yelling to move the bikes, the driver insisting everyone wait for police, and finally helping lift 120 kilos with adrenaline-numbed arms. Julia collects her amnesty on the spot: 'ya no me puedes juzgar' for her two frozen minutes over the bug in his ear.
El gimnasio del futuro
“Hoy no necesitamos levantar cosas pesadas, para eso hay máquinas, ¿y por qué la gente levanta pesas? Aprender será en el futuro lo que hoy es el gimnasio. Y existirán powerlifters del estudio: gente que aprende más rápido y quiere ser la que más sabe.”
“We don't need to lift heavy things today, machines do that, so why do people lift weights? Learning will be to the future what the gym is to us now. And there will be powerlifters of study: people who learn faster and want to be the ones who know the most.”
Karpathy's analogy from the interview they've been mining for days, landing on a couple that builds language apps: post-AGI, education survives as chosen strength. The adjacent bar Karpathy set matters to Severo directly: a good human tutor gauges your level within ten minutes of conversation, and the AI tutor that can do that doesn't exist yet.
La radio personalizada
“La radio no era tan viciante porque no existía una radio personalizada: tenían que escoger lo que le gustara a la mayoría. Los algoritmos de hoy, que funcionan con reinforcement learning, se adaptan a ti. Y me da curiosidad: ¿las personas ciegas serán viciadas a alguna red social como nosotros a TikTok?”
“Radio wasn't that addictive because personalized radio didn't exist: they had to pick what the majority would like. Today's algorithms, which run on reinforcement learning, adapt to you. And I'm curious: are blind people hooked on some social network the way we are on TikTok?”
A tangent inside the creativity debate: vision as the addiction surface (the eye is a recognition machine, which is why colorful-and-confusing wins clicks), the open research question about blind users and infinite scrolls, and the confident aside that if TikTok's team built a Spotify seriously, 'estaríamos hasta acá todo el día escuchando música.'
El camión de abejas
“En Rumania tienen un camión móvil de abejas para polinizar los campos. Y existe el robo de abejas: dejan los tráilers días en el campo y la gente para, rompe las colmenas y las redistribuye en cajas nuevas para que no haya rastro. ¿A quién se le ocurre robar abejas?”
“In Romania they have a mobile bee truck to pollinate the fields. And bee theft exists: the trailers sit in the fields for days and people stop, break up the hives and redistribute them into new boxes so there's no trace. Who thinks of stealing bees?”
A Reddit rabbit hole on pollination-as-a-service: portable hives, portable honey, good money and real risk, one raided trailer can erase a beekeeper's entire capital. The reason the truck exists at all closes the loop grimly: pesticides killed the wild bees that used to do the job for free.
La pastilla en el pollo
“La papaya funcionó un día: como es aguada, la pastilla se desintegra y él la lee. El pollo no es aguado y huele más fuerte: uno empuja la pastilla adentro y él la traga, porque le sabe más a pollo que a pastilla.”
“The papaya worked for one day: since it's watery, the pill disintegrates and he reads it. Chicken isn't watery and smells stronger: you push the pill inside and he swallows it, because it tastes more like chicken than pill.”
The megatip from Thor's urinary-infection treatment, offered to the audience after the papaya method was defeated by canine forensics on day two. Recovery proceeding 'a punta de amor': walked yesterday, sat, walked back. Better than two days ago, not yet what he was two weeks ago.
Google es Google
“Google es Google, lo demás es lo demás. Llegaron tarde a la lucha pero llegaron fuertes: un IDE gratis con cinco modelos buenos, hasta Sonnet 4.5. Claude nunca ha regalado créditos así, GPT te cobra hasta para probar la API. Es muy agresivo.”
“Google is Google, everything else is everything else. They arrived late to the fight but arrived strong: a free IDE with five good models, even Sonnet 4.5. Claude has never given credits away like that, GPT charges you even to try the API. It's very aggressive.”
Reviewing Antigravity, Google's new IDE, the day after the Claude ban: parallel agent chats, plan artifacts, one-click commit messages, a browser extension that tests your app and hands back a video, and no visible context window to manage. The irony he savors: the exact model they were paying $100 for is now free inside the giant's editor. The lineage recap: VS Code, forked by Cursor into billions, forked again by Windsurf, and now the city arrives next to the huts.
El último sueño
“Imagínense que se rompa el tubo a las 2 de la mañana. No despiertas. O sea, no despiertas: el último sueño es el de la vida. La vida de uno parece segura, pero no es tan segura como uno piensa.”
“Imagine the pipe breaking at 2 in the morning. You don't wake up. I mean it: you don't wake up; your last dream is life's last. Your life looks safe, but it isn't as safe as you think.”
A construction crew across the street ruptured the gas main during their emergency call about the Claude ban: firefighters, the only exit road closed, and half an hour of dizzy, floating, autopilot cognition, menus suddenly hard to read, until ice cream and distance cleared it. Collateral detail: a trucker trapped by the leak missed Chía's curfew window and sat three extra hours, gajes del oficio.
El feeling humano
“Intentó automatizarlo con bots y dijo: 'la IA todavía no consigue ese feeling humano; somos cuatro o cinco personas hablando con la gente.' Imagínate enamorarte, querer conocerla, y después de uno o dos años darte cuenta de que es todo falso.”
“He tried automating it with bots and said: 'AI still can't get that human feeling; we're four or five people talking with the customers.' Imagine falling in love, wanting to meet her, and after a year or two finding out it was all fake.”
A Redditor reporting $440,000 since late 2023 from AI-generated influencer models funneled to pay-to-chat platforms, where the one thing that couldn't be automated was the conversation itself. The platforms nominally ban AI content; the workaround holds. Filed with the Comet bot that auto-replies to fan posts: soon you won't know who you're talking to, and your idol's reply may be selling you creatine.
La maldición del profesor
“Nosotros no le hacemos daño absolutamente a nadie; siempre le deseamos el bien a todo el mundo. Entonces, ¿quién nos pudo haber puesto una maldición? La teoría es que posiblemente sea un profesor... y medio que coincide con cuando comenzaron a salir todas las cosas mal.”
“We don't harm absolutely anyone; we wish everyone well. So who could have put a curse on us? The theory is it's probably a professor... and it roughly coincides with when everything started going wrong.”
The two least superstitious people on the channel, cornered by a year of thirty ghosted opportunities, produce their only suspect: the psycho-rigid professor from his final semester, who corrected values without ever explaining why, and whose life the class, led by him, made difficult in return. Restitution is considered and declined: 'igual, perdonado.'
Un bot que no es bot
“Me escribe una 'editora de TikTok': solo debes ver videos, dar like y enviarme la captura; pago 5.000 por video. Si trabajara en eso, me estarían pagando por ser un bot más: un bot que no es bot porque es una persona real. Y un amigo que maneja redes me dijo: 'hoy en día, el que no utilice bots se está quedando atrás.'”
“A 'TikTok editor' messages me: you just watch videos, like them and send me the screenshot; I pay 5,000 per video. If I took that job, they'd be paying me to be one more bot: a bot that isn't a bot because it's a real person. And a friend who runs social accounts told me: 'these days, whoever isn't using bots is falling behind.'”
The cold call from 'servicio profesional de enfermería' offering 300-500 thousand pesos a day for likes, read as the decentralized human click farm, India's engagement factories gone gig-economy. The unresolved worry he says out loud: whether everyone big on the internet first bought their gravity with bots and only later stopped needing them, 'si es así, realmente es muy triste.'
Dos papers después
“No más agencias de publicidad: puedes crear 100,000 anuncios con unos pocos dólares, mantener al actor consistente, y gastar unas semanas en un workflow que copias. Esto solía valer $100,000. Y como dicen: imagínense dos papers más adelante; si esto es Sora 2, imagínese Sora 3.”
“No more ad agencies: you can create 100,000 ads for a few dollars, keep the actor consistent, and spend a few weeks on a workflow you then copy. This used to cost $100,000. And as they say: imagine where we'll be two papers down the line; if this is Sora 2, imagine Sora 3.”
An X post showing a full AI-generated Nike ad beside its scene-by-scene generation workflow, the creator directing each cut. It confirms a prediction he claims from two years back: everyone becomes their own director, their own chef, their own boss. Julia's one-word review of the output economy: 'mucha chuchafita.'
La startup de dos líderes
“Imagínense una startup de cinco personas donde solo nos hablábamos el domingo, comunicación rotísima, y con dos líderes: uno dice 'vamos a hacer esto' y el otro dice 'no, mejor vamos a hacer esto otro.' Fue una de las que nos salvamos.”
“Imagine a five-person startup where we only talked on Sundays, communication utterly broken, and with two leaders: one says 'let's do this' and the other says 'no, better we do this other thing.' It's one of the ones we were saved from.”
Barberos Club, the near-miss: two lawyer friends proposed founding a five-person company with the LuarAI trio. Nobody answered messages during the week, and the second natural leader guaranteed a permanent steering war. They walked before signing; the friendship survived, and there's a pending offer to teach the man vibe coding on camera.
Dos tarros y un procesador
“Salieron dos potes de crema de avellana por el precio de uno, como 40% menos... y se dañó el procesador. Yo creo que hubiera salido más barato comprar dos tarros de Nutella, pero lo importante es el aprendizaje.”
“We got two jars of hazelnut cream for the price of one, about 40% less... and the food processor died. I think buying two jars of Nutella would have come out cheaper, but what matters is the learning.”
Julia finally manufactures the dream from her Nutella prophecy: half a pound of hazelnuts, cacao, vanilla, sunflower oil, milk. Unit economics excellent, consistency too liquid, motor burned out mid-grind, RIP processor, following the vacuum cleaner. The recipe enters iteration; the appliance enters legend.
La Navidad generada
“Está tan bien hecho que es totalmente pasable; yo pensaría que es un 3D, un render. Imagínate cuánta plata no gastaban antes produciendo un video de calidad, y hoy una sola persona en dos semanas lo saca.”
“It's so well made it passes completely; I'd have guessed it was 3D, a render. Imagine how much money they used to spend producing a quality ad, and today a single person turns it out in two weeks.”
Watching Coca-Cola's AI-generated Christmas ads, 2024 next to 2025, credited on screen to the company's own 'Real Magic AI' team. Julia mistook the new one for a conventional render, which is the point: the evidence against the 'AI means low quality' reflex is airing on television, one production-cost collapse at a time.
El examen antes de la entrevista
“No te han hecho ni la primera entrevista y ya te dicen 'vaya, hágase exámenes médicos.' Lo hacen para curarse en salud: revisan tu estado inicial y tu estado final, y si después los intentas demandar, 'yo puedo testificar el estado inicial y el estado final.'”
“They haven't even given you the first interview and they're already telling you 'go get medical exams.' They do it to cover themselves: they record your initial state and your final state, and if you try to sue later, 'I can testify to the initial state and the final state.'”
Carlos's hiring process: three trips to Bogotá and pre-interview medical exams for a job he still doesn't know he has. Julia's Brazilian baseline is that exams come after you're hired, on the company's dime. His decoding of the Colombian practice as liability bookkeeping lands next to the polygraph story from days earlier: the candidate pays the trust tax up front.
Veinte de Divo
“No hemos hecho revenue... bueno, realmente lo hemos hecho: 20, en Divo, que pensábamos que iba a ser un ingreso recurrente, pero no. El man después canceló la tarjeta. Y por cierto, Divo no sé qué pasó, no está funcionando.”
“We haven't made revenue... well, actually we have: 20, on Divo, which we thought would be recurring income, but no. The guy later canceled his card. And by the way, Divo, I don't know what happened, it isn't working.”
The complete revenue ledger of the company's first year-plus, stated in one breath: a single Divo subscription, since churned, on an app that's currently down. Said inside the honest stretch about being far from any entrepreneurial environment, 'picado aquí, picado acá,' and why proximity to mentors, like the program he's interviewing for, might be worth more than the salary.
Devueltos de Florianópolis
“Es como prevenir a alguien de la costa de venir a Boyacá sin ningún objetivo. ¿Y si yo quiero rehacer mi vida? Esto es superilegal, xenofobia, y ni siquiera llegan extranjeros: llegan brasileros.”
“It's like barring someone from the coast from coming to Boyacá without a stated purpose. And what if I want to rebuild my life? This is wildly illegal, xenophobia, and they aren't even foreigners arriving: they're Brazilians.”
Florianópolis's mayor films himself at the bus terminal boasting that social-assistance teams 'return' arrivals with no job, family, or address, 500-plus people sent back with a paid ticket. It lands on a memory: three years ago, sick and cold in that same terminal at midnight, they were the only travelers in all of Brazil ordered off the floor by security. Julia's verdict, borrowed from a commenter: 'siempre esperemos lo peor del sur y ellos entregan.'
Pan con Coca-Cola
“Si esto es tan común, esa combinación de pan y Coca-Cola debe tener algo que realmente les dé energía. Debe ser la combinación perfecta que da la energía necesaria, apenas, para completar el trabajo del día.”
“If this is so common, that bread-and-Coca-Cola combination must have something that genuinely gives them energy. It must be the perfect combination that delivers just enough energy to finish the day's work.”
Field observation at a construction site near the house: a 3-liter Coke and two bags of bread feeding five or six workers at lunch, roughly 8,000 pesos total. The live AI search finds no formal studies, just the obvious mechanics, fast carbohydrates and sugar, Julia's 'inyección de insulina.' Filed alongside the obrero starter pack: one in ten carries a Barbie backpack.
La carroza sin caballo
“Parece un carruaje, una carroza sin caballo; lo único que falta es ponerle sonidos de cascos. Primero se van a automatizar las cosas que ya existen y producen valor.”
“It looks like a carriage, a horseless carriage; all it's missing is hoof sounds. The first things to be automated will be the things that already exist and already produce value.”
Watching a four-seat driverless robotaxi merge onto a Las Vegas artery. Julia's dream use case is the long haul: rent one for a week, São Paulo to Minas, playing cards while it drives, telling the AI to stop at the best-reviewed arepa place. His automation ordering: intercity buses that today carry two alternating drivers go first, and vehicle-to-vehicle coordination could make single-lane Colombian roads as fast as highways just by deleting accidents.
Copiar y mejorar
“Copiar lo que ya funciona yo no lo veo mal. No necesitamos reinventar la rueda: copiar lo que ya está bueno y mejorar lo que puede ser mejorado.”
“Copying what already works, I don't see it as bad. We don't need to reinvent the wheel: copy what's already good and improve what can be improved.”
Julia's counterweight after the deep search showed the digital-menu market full of mature POS suites. Where he reaches for the disruptive new feature, she votes to replicate the proven baseline and out-execute on the weak spots, her example being inventory modules that demand more bookkeeping than a small restaurant needs.
Una IA juez
“Esto es una IA en una plataforma, YouTube. Ahora imagínate una IA en el gobierno, una IA juez: 'para la cárcel.' ¿Por qué? 'Porque la ley lo dice.' Y tú no has hecho nada.”
“This is an AI on one platform, YouTube. Now imagine an AI in government, an AI judge: 'off to prison.' Why? 'Because the law says so.' And you haven't done anything.”
Prompted by the wave of YouTube channels terminated by an AI moderator with deletion authority: a large Minecraft creator's channel killed for being 'linked' to a copyright-struck channel that was in Japanese, no appeal offered, four or five similar cases in a day. His read: a preview of the dystopia where automated enforcement gets the last word, versus the older regime where a human appeal undid the error.
Taladrar la cabeza
“Le dijo a la novia 'boba', así de chiste. Uno comienza a hacerlo así y termina siendo tan inconsciente, y llega un punto en donde ya taladró tanto en la cabeza de la persona que la persona se lo va a creer: 'ah, yo soy boba.'”
“He called his girlfriend 'silly,' as a joke. You start doing it like that and it becomes so unconscious, and there comes a point where it has drilled so deep into the person's head that they believe it: 'ah, I am silly.'”
Overheard at the hot springs, a young couple, filed under vocabulary-as-habit. The counterweight in the same conversation is ChatGPT's relentless encouragement: told 'you'll get there' often enough, you believe that instead, 'hay que creérselo.' Same drilling mechanism, opposite payloads.
El chat temporal
“Mi proyecto se fue a popó. Yo estaba muy feliz con mi proyecto y mi Windows se actualizó... porque estaba en chat temporal. Toda mi semana que yo estuve trabajando.”
“My project went to poop. I was so happy with my project and my Windows updated... because I was in a temporary chat. My whole week of work.”
Julia's first programmer heartbreak: a week of Piqui-bar logic built inside Google AI Studio's temporary chat, wiped by a Windows update. The person who suggested the temporary chat ('no voy a citar nombres') concedes it's happened to him too, about four times, since temporary mode can't be converted to a saved chat mid-conversation. The consolation is the oldest one: 'al final todo está acá en la cabeza.'
Comer mierda propia
“Cuando uno está en un trabajo, uno come mierda del jefe o de alguien más. Entre comer mierda de alguien más y comer mi mierda, prefiero la mía. Porque yo puedo escoger lo que como.”
“When you're at a job, you eat the boss's shit, or somebody else's. Between eating someone else's shit and eating my own, I'll take mine. Because I get to choose what I eat.”
His crude, load-bearing argument for entrepreneurship after a year without income and four fried days of programming. Julia gets there first and funnier: asked whose she'd eat, she answers 'la mía, porque yo puedo escoger lo que como... yo pongo la dieta, voy testando.' The honest coda: both diets hurt, the blank page is a double-edged sword, but autonomy wins at long horizon.
Si yo quisiera WhatsApp
“Tú empiezas la llamada, clica uno, clica dos, clica uno, dos, tres, cuatro... 'ya, seguiremos nuestro atendimiento por WhatsApp.' Si yo quisiera por WhatsApp, yo hubiera llamado por WhatsApp.”
“You start the call, press one, press two, press one, two, three, four... 'right, we'll continue your service on WhatsApp.' If I'd wanted WhatsApp, I would have called on WhatsApp.”
Validation-week status on the phone-menu idea: the customer-side pain is '100% validado,' every Colombian and Brazilian caller can testify, Julia's own Claro saga included. The missing half is why companies tolerate it: nobody has yet reached a purchasing-side director who can say whether the reason is cost, ignorance, or 'good enough.'
Las ventajas de los drones
“Nosotros les vemos muchas ventajas a los drones, el delivery, el transporte. Pero lo loco es que la mayoría de ventajas que la gente les encuentra actualmente son temas de guerra: una cosa barata que tú puedes maniobrar y llegar a cualquier lugar rápidamente.”
“We see so many upsides in drones, delivery, transport. But the crazy thing is that most of the upsides people are finding for them right now are war uses: something cheap you can maneuver and get anywhere fast.”
Said while processing the Rio de Janeiro mega-operation against the Comando Vermelho, 120-plus dead, consumer drones adapted to drop bombs on police, and the Ukraine footage of a Russian soldier who simply sat down when the kamikaze drone hovered to film his face. The dual-use lament from two people who once dreamed of drone delivery.
¿Qué es polenta?
“Muy probablemente tú ya comiste polenta 500 veces, de mi mamá, de mí, y todavía preguntas '¿qué es polenta?'. Vamos a aprender qué es polenta en vivo; yo creo que después de esto no se me va a olvidar.”
“You've very probably eaten polenta 500 times, my mom's, mine, and you still ask 'what's polenta?'. Let's learn what polenta is live; I think after this I won't forget it.”
Julia's counter-evidence in the memory episode: the vitamins fixed his recall of client meetings, but polenta remains unretained after years of exposure. His defense is the selective-memory clause, interest gates recall, 'de qué me sirve aprenderme el nombre si tú vas a cocinar.' They google it together on camera as a fix.
Cuénteme sobre usted
“Después de una carrera exitosa en tech, me di cuenta de que mi verdadera pasión no era optimizar sistemas existentes, sino crear soluciones desde cero. El éxito no es tener una idea brillante, sino el proceso riguroso de iterar y validar esa idea hasta encontrar el product market fit.”
“After a successful career in tech, I realized my true passion wasn't optimizing existing systems but creating solutions from zero. Success isn't having a brilliant idea; it's the rigorous process of iterating and validating that idea until you find product market fit.”
Gemini's post-mortem script for the Girdley interview's opener, 'cuénteme un poquito sobre usted,' which he'd answered improvised. His review: 'si yo hubiera dicho esto, lo hubiera roto desde el principio, 10 de 10.' Next stage is a 4-day assessment, build something you've never built before, with AI, and the idea he's circling is automating their video clips into shorts.
La cláusula del neurocirujano
“Imagínate una cláusula de confidencialidad de un neurocirujano: 'listo, usted aprendió neurocirugía aquí, pero no puede volver a hacer neurocirugía en su vida, porque usted me debe el alma.' Esas cláusulas deberían ser ilegales.”
“Imagine a confidentiality clause on a neurosurgeon: 'fine, you learned neurosurgery here, but you can never do neurosurgery again in your life, because you owe me your soul.' Those clauses should be illegal.”
The partner assigned to validate the phone-menu idea won't work on it, citing a two-year confidentiality clause from his last job, and won't even share the clause's text. Juan Pablo's research suggests such clauses may only bind if extra compensation was paid. The sharper worry is the pattern: 'y si... y si... y si...', any blocker on the road becomes a no, 'se queda una persona difícil de trabajar.'
Veinte toneladas de Nutella
“Yo soñé que la Nutella estaba de promoción, muy barata, y que compré 20 toneladas de Nutella. Y desde entonces Julia tiene que comprarse una Nutella cada mes y medio.”
“I dreamed Nutella was on sale, dirt cheap, and that I bought 20 tons of Nutella. And ever since, Julia has to buy herself a Nutella every month and a half.”
Julia's contribution to the dream-interpretation segment, offered deadpan as a case for ChatGPT analysis ('¿qué significa soñar que tengo Nutella infinita en mi casa?'). The dream turned out to be mildly prophetic: the promotion was real. He claims the purchases are weekly; she holds the line at every month and a half.
Más de 30 no
“Mi predicción, ya creo que lo he dicho: Estados Unidos se va a separar. No sé si va a ser en 2 años o en 10 o en 20, pero más de 30 no. Se va a dividir, no sé si en dos o en tres.”
“My prediction, I think I've said it before: the United States is going to come apart. I don't know if it'll be in 2 years or 10 or 20, but not more than 30. It's going to split, I don't know whether in two or in three.”
Recorded on camera after watching ICE agents drag a mother from a school corridor while her child screamed, ten agents to one person, faces masked. His reading: the agents are paid, not ideological ('vendieron su alma'), the printed money financing it debases everyone else's, and the real driver is a government setting people against people while the resentment compounds. Julia's counter-scenario: an attempted seizure of power by force rather than a clean split.
Reimaginar
“Esa palabra es muy importante, reimaginar. Porque si uno simplemente dice 'haga un nuevo logo con estos dos', queda una cosa medio mal cocinada. Cuando le dices que reimagine este en el estilo del otro, boom, cambia la perspectiva. Cosas de prompt engineering que uno va cogiendo a poquito.”
“That word matters a lot: reimagine. If you just say 'make a new logo out of these two,' you get something half-baked. When you tell it to reimagine this one in the style of the other, boom, the perspective shifts. Prompt-engineering habits you pick up bit by bit.”
The vibe-coding group ran a mini hackathon: redesign the Internet Explorer logo. Everyone else's Gemini output looked generic; his two-minute entry fused the old IE 'e' with Copilot's ribbon by prompting Nano Banana to reimagine one in the style of the other, and the group crowned it 'the child of Edge and Copilot.'
The sign that invited the theft
“En el metro de Nueva York, por una subida de robos, pusieron un letrero que decía 'cuide sus pertenencias'. Al verlo, la gente se iba a tocar el bolsillo donde tenía lo de valor, y los ladrones ya sabían dónde estaba. En vez de disminuir, los robos aumentaron.”
“In the New York subway, after a rise in thefts, they put up a sign reading 'watch your belongings.' Seeing it, people would touch the pocket where they kept their valuables, and the thieves now knew exactly where they were. Instead of dropping, the thefts went up.”
His argument for killing the fifth brainstorm idea, a dedicated safe place to meet for online-purchase exchanges: the same logic applies. A spot advertised as the place to swap cash and goods becomes an easy target, a thief just waits for someone to walk out with money or a product. A signal meant to protect can hand attackers the very information they needed.
Whack-a-mole
“Sería interesante compilar los errores más frecuentes de la IA según el framework: el race condition, cuando se ejecuta en desorden y el primero nunca corre; y el whack-a-mole, cuando resuelves un problema y aparece otro que estaba oculto, un paso adelante, dos para atrás.”
“It'd be interesting to compile AI's most frequent errors by framework: the race condition, when things run out of order and the first never executes; and whack-a-mole, when you fix one problem and another hidden one surfaces, one step forward, two back.”
A Severo dev observation turned proposal for the vibe-coding group: catalog the recurring failure modes of AI-generated code per framework so they can be spotted and fixed faster. Julia's analogy for the race condition: the reading-comprehension exams where five questions hang off one passage, so getting the first wrong dooms all five.
Caramelo
“En Brasil le decimos 'caramelo' a los perros callejeros de color amarillito. Vimos la película Caramelo y a mí se me salieron unas lagrimitas, porque me puse a pensar en Thor.”
“In Brazil we call the yellowish street dogs 'caramelo.' We watched the film Caramelo and I teared up, because I started thinking about Thor.”
A Brazilian Netflix film (predictable first 40 minutes, then a terminal-illness turn that undoes both of them) watched the same week Thor had his best day yet, walking to the grass and playing with the tennis ball after weeks down. His unanswered question about the film doubles as a note on the dog: whether deep bonds really form fastest in shared hardship, 'cuando uno está en una situación muy mala junto con otra persona.'
Más ingredientes que una bomba atómica
“Este Gansito tiene más ingredientes que una bomba atómica. La bomba atómica tiene solamente como dos ingredientes. Contiene tartracina, colorante secuestrante... rompimos nuestro juramento de vegetarianismo.”
“This Gansito has more ingredients than an atomic bomb. The atomic bomb only has about two ingredients. It contains tartrazine, a sequestrant coloring... we broke our vegetarian vow.”
A cold-open taste test of a zombie tongue-painting Gansito, an irresistible 2,200-peso impulse buy, that turns into reading the ingredient label aloud in horror (tartrazine, sequestrants, a dozen emulsifiers) and a mild betrayal of vegetarianism over the gelatin question, resolved by agar-agar. The tongue, promised painted, stayed unpainted: 'falsísimo.'
La tienda que se mueve
“Un man hizo una automatización en n8n que hace scrap del catálogo de una tienda, coge cada imagen estática y la pasa por Veo 3, y ya cada foto de ropa se anima: la modelo se mueve, se ve el caimiento de la ropa. En simples clics tu tienda estática se vuelve inmersiva.”
“A guy built an n8n automation that scrapes a store's catalog, takes each static image and runs it through Veo 3, and now every clothing photo animates: the model moves, you see how the fabric falls. In a few clicks your static store becomes immersive.”
A workflow that turns a static e-commerce gallery into video product shots, saving the cost of models and film crews, animating garments so you can see how they drape. Filed as the recurring pattern he keeps flagging: a simple pipeline (scrape → per-image generation → assemble) that professionalizes a whole category of work, and another expensive skill (fashion photography) getting leveled by a few clicks.
El conejillo de indias
“Me puse una vacuna experimental de Sanofi porque quería viajar lo antes posible. Yo pensaba que tenía el placebo todo el tiempo, hasta que me pusieron la segunda dosis y me dio COVID. Ahí supe que era la real.”
“I took an experimental Sanofi vaccine because I wanted to travel as soon as possible. I thought I had the placebo the whole time, until they gave me the second dose and I got COVID. That's when I knew it was the real one.”
The BAC-002 trial (phase 2, later shelved when Sanofi partnered with Novavax; results were positive, 95-100% neutralizing antibodies). They paid ~100k pesos and a boxed lunch per visit; a botched blood draw nearly made him faint. He had to formally unblind himself to get a travel-certified vaccine (AstraZeneca) so he could fly to Brazil to meet Julia, the trip that started this whole diary.
El primer pedido genuino
“Compramos la misma crema Scala en la misma tienda de siempre, y llegó falsificada: sin el QR de verificación, con un sello de cinta en vez del plástico, y olor distinto. Quizás mandan el primero genuino y, cuando ya confías, empiezan a mandar el falso.”
“We bought the same Scala cream from the same store as always, and it arrived counterfeit: no verification QR, taped shut instead of sealed, different smell. Maybe they send the first one genuine, and once you trust them, they start sending the fake.”
A Brazilian hair-cream brand (23,000 COP, not even expensive) faked on a Colombian marketplace. Julia's unease is the entry: a product she trusted her whole life in Brazil, counterfeited the moment it crossed the border. The bait-and-switch hypothesis, genuine first order to earn trust, fake thereafter, as a marketplace-fraud pattern; the QR-code authenticity check as the giveaway.
No hay Spotify para libros
“Estamos en 2025 donde podemos escuchar cualquier canción con un clic, pero aún no podemos leer cualquier libro con una suscripción. Kindle Unlimited paga por páginas leídas, igual que Spotify, pero excluye los bestsellers.”
“It's 2025 and we can hear any song with one click, but we still can't read any book with one subscription. Kindle Unlimited pays authors by pages read, just like Spotify, but it excludes the bestsellers.”
The 'why no Spotify for books' investigation. Kindle Unlimited's per-page model mirrors Spotify's per-stream, but bestsellers stay out to protect direct sales (Amazon's rule, same as Prime Video renting new releases). Julia's better answer: it's a demand problem, reading is more selective and slower than music, which is consumed passively and in volume. Nobody asked for it because the new generations are on the phone, not the page.
¿Prolongar o dignificar?
“Al final, en nuestra ingenuidad, ¿estamos prolongando el sufrimiento del perro, o realmente puede mejorar un poquito y terminar esos últimos días con un poco más de dignidad?”
“In the end, in our naivety, are we prolonging the dog's suffering, or can he really improve a little and finish these last days with a bit more dignity?”
A hard Thor day: barely walked, vomited his dinner, blood from the urethra, plus a salt-poisoning near-miss when Julia salted his chicken by instinct and they had to rinse it. The emotional exhaustion of optimism named out loud: 'uno le da toda la energía, sí se va a recuperar, y después pareciera que está igual.' The vet believes he's suffering; they believe he can recover. The question left open, honestly, on both sides.
Mercado para dos meses
“Entramos a buscar la Nutella y salimos con 17.5 kilos de comida por 175 mil pesos. Eso mismo en un Carulla sería más de un millón, sin molestar. Vamos a comer mucho falafel.”
“We went in for the Nutella and left with 17.5 kilos of food for 175 thousand pesos. That same haul at Carulla would be over a million, no joke. We're going to eat a lot of falafel.”
After the investment meeting, a browse at Makro (Colombia's closest thing to a Brazilian atacadista) becomes an accidental two-month grocery run: 3 kg chickpeas, 5 kg rice, spices at 125g for the price of 25g elsewhere. The nuance he flags: bulk stores mix wholesale staples (cheap) with industrialized products (normal price), so only the unprocessed food actually saves. The Nutella they came for was discontinued.
Lo que no puedo crear, no lo entiendo
“What I cannot create, I don't understand. Rauch lo citaba distinto: si quieres entender React, intenta hacer una copia de React. Cuando uno lo rehace, uno termina entendiendo qué funciona y qué no.”
“What I cannot create, I don't understand. Rauch cited it differently: if you want to understand React, try making a copy of React. When you rebuild it, you end up understanding what works and what doesn't.”
Richard Feynman's line, surfaced via Guillermo Rauch, paired with a childhood meme he remembered: a guy filming himself disassembling his PC so he could play the video backward to learn how to reassemble it, because first-time disassembly always ends with five leftover screws. Understanding as a reversible operation you have to run forward yourself.
Reaprender el cuerpo
“Es como de repente estar en un cuerpo diferente: todas las cosas que tú sabías, los movimientos, como que ya no sirven. Tienes que reaprender todo.”
“It's like suddenly being in a different body: everything you knew, the movements, they no longer work. You have to relearn everything.”
Said about Thor, home from the vet with suspected neurological damage, a catheter the veterinarian left in anticipating a decision the family hasn't made. His counterargument to euthanasia is this frame: not a broken dog but a dog in an unfamiliar body, plus the confession that one reason he lifts weights is to be able to lift a 37-kilo shepherd. 'Yo aún creo que el perro tiene ánimos.'
Los pentágonos abiertos
“Un matemático encontró cinco pentágonos que sí sirven para tiling y dijo: posiblemente no hay más. Llegó otro y encontró tres más, y demostró que ya no había. Hasta que llegó una señora en su casa, leyó el paper, y encontró otro.”
“A mathematician found five pentagons that do tile the plane and said: there are probably no more. Another came and found three more, and proved that was all. Until a woman at home read the paper and found another.”
The pentagon-tiling problem as bedtime dato perturbador: triangles, squares, and hexagons tile trivially; regular pentagons never do; fifteen exceptional pentagon families are known, several found by an amateur, and every discoverer thought theirs was the last. Filed as his favorite genre: an open problem where the credentialed keep declaring closure and the kitchen table keeps reopening it.
El secreto es oler mal
“En el gimnasio nunca nadie viene a darnos consejos, o hace rato no me pasaba. Y hoy, dos veces en el mismo día, dándonos tips. Y yo todo el día olí a perro.”
“At the gym nobody ever comes to give us advice, or it hadn't happened in ages. And today, twice in the same day, people giving us tips. And I smelled like dog all day.”
Same session: one stranger arrived with muscle-anatomy photos pre-loaded to correct his grip width, and another taught a two-in-one bicep curl by pushing the dumbbell down mid-rep to force slow negatives, then told him he smelled like dog (he did; he'd carried Thor all morning). Unsolicited gym expertise as a natural phenomenon awaiting its theory.
Sin compromiso con nadie
“Lo que pasa con estas plataformas como Didi es que me dan flexibilidad. Yo trabajo cuando quiera. Los que trabajamos en aplicaciones no tenemos compromiso con nadie.”
“The thing about these platforms like Didi is they give me flexibility. I work whenever I want. Those of us who work on apps have no commitment to anybody.”
Henry, a bicycle courier in Chía, rejecting their fixed-salary pitch on the spot. The naive model said gig platforms exploit workers who'd prefer stability; the worker himself priced independence above social security. A datum that complicates every future Tencargo compensation design.
Conectar personas
“Tú creas valor cuando consigues conectar a personas, cuando consigues hacer que alguien haga algo diferente gracias a ti.”
“You create value when you manage to connect people, when you manage to make someone do something different because of you.”
Said while closing the exploration phase (Firebase, Stripe, RevenueCat, Flutter, all learned) and turning to Tencargo's street work. A definition of value with no technology in it, arrived at after two months of the REAPRA method insisting on exactly that.
El dopaje de hardware
“Si lo miro en deportes, el mérito ya no es del atleta. Una persona ya no está preocupada por ser el mejor del mundo como Cristiano Ronaldo, sino: compré un equipamiento mejor y ya, yo corro más rápido.”
“If I look at it in sports, the merit is no longer the athlete's. A person no longer cares about being the best in the world like Cristiano Ronaldo, but: I bought better equipment and that's it, I run faster.”
Watching a Chinese hip-exoskeleton belt ('it's moving for me, I'm not walking') priced startlingly low. The couple's split verdict: miraculous for grandparents and limited mobility, corrosive for sport; plus his joke that won't stay a joke, outsourcing the walk itself while the owner sleeps through the marathon.
Promete domingo, entrega miércoles
“En teoría iba a llegar este domingo y llegó hoy miércoles. No sé si dicen eso como para tener unas expectativas acá y después mejorarlas, y uno tener una mejor percepción.”
“In theory it was arriving this Sunday and it showed up today, Wednesday. I don't know if they say that to set expectations low and then beat them, so you come away with a better perception.”
The DJI mic bought on Amazon for 420,000 pesos (versus 800,000 locally) arrived in three days against a week's estimate. His off-hand theory names under-promise-over-deliver as a deliberate logistics UX pattern; also the moment the 'Chinese products are bad' prejudice died in his hands.
Siempre ha sido así
“Le pregunté a la señora: vecina, ¿tiene iris? Y dijo: no, eso se vende en las droguerías. Le pregunté por qué, y otra señora dijo: sí es muy raro, pero eso toda la vida ha sido así.”
“I asked the shopkeeper: ma'am, do you have fabric dye? And she said: no, that's sold at drugstores. I asked why, and another lady said: it is strange, yes, but it's been that way forever.”
Fabric dye in Colombia is sold at pharmacies, not sewing shops, and nobody in the chain, seller or buyer, knows why; the live AI investigation returned only 'market evolution' hand-waving. Filed as a specimen of institutional inertia: an equilibrium everyone maintains and no one can explain.
El 2050 de Julia
“Yo pienso que va a ser caótico. Una extrema crisis política y financiera, como la IA ya va a sustituir el 80% de los trabajos, y un 70% de la población mundial va a estar en la línea de pobreza.”
“I think it's going to be chaotic. An extreme political and financial crisis, since AI will have replaced 80% of jobs, and 70% of the world's population will be at the poverty line.”
Her cold-open answer to 'how will the world be in 2050,' delivered before the time capsule was even announced; she adds a maybe-World-War-III. Filed as a dated prediction the channel can grade in twenty-five years, against his own sunnier 5-to-10-year timelines elsewhere.
La IA, hija del capitalismo
“¿Será que la inteligencia artificial es el resultado del mundo capitalista en el que vivimos? ¿Tú crees que en otro sistema se priorizaría tanto la productividad y el dinero?”
“Could it be that artificial intelligence is the product of the capitalist world we live in? Do you think another system would prioritize productivity and money this much?”
Asked right after wondering what Sam Altman actually wants (his guess: a girlfriend like in Her). Julia's answer points the other way: with essentials guaranteed, people would be freer, not less productive. The question of whether a different economy would have built a different intelligence, left open.
El solo founder
“Hay una tendencia en los venture capital de que hoy en día hay más solo founders que founders grupales. Feo porque hay más individualidad, pero tú te puedes mover mucho más rápido solo.”
“There's a trend in venture capital where today there are more solo founders than founder teams. Ugly because there's more individualism, but you can move much faster alone.”
Cited alongside Sam Altman's line that the next billion-dollar company will be built by one person. Left hanging over a channel run by a couple and a company of two: if the tools reward moving alone, what's the new argument for building together?
El papá compositor
“Mi papá descargó Suno y se la ha pasado maravilladísimo, que porque le hace los coros, le hace toda la instrumentación, la saca en diferentes estilos. Está enamoradísimo.”
“My dad downloaded Suno and he's been absolutely marveling at it, because it does the choruses for him, does all the instrumentation, renders it in different styles. He's head over heels.”
His father doesn't type; he opens the keyboard microphone and speaks the lyrics: 'mi gatico, miau miau miau.' One of five generated versions came out genuinely catchy, got a Veo video, and got published. The adoption curve nobody predicted: a Colombian dad writing songs for the house pets by voice.
La información robada
“Es chistoso porque al final es como que estamos robando información de toda internet para hacer este modelo, y después estamos cobrando por lo que se generó con esta información robada.”
“It's funny because in the end it's like we're stealing information from the whole internet to build this model, and then we're charging for what gets generated with that stolen information.”
Raised while wondering whether Suno users own the songs they generate; the terms he's seen say the platform owns your output unless you pay. The copyright question left open on camera: who gets sued, the person who prompted the cat song or the company that ate the training data?
Una casa en la floresta
“Si yo tengo un hijo, no me gustaría que tuviera acceso a redes sociales. Siempre me suena esta película cuando pienso en un futuro así medio ideal.”
“If I have a kid someday, I wouldn't want them to have access to social media. That film always comes to mind when I imagine a half-ideal future like that.”
Julia's answer to the Sora-feed conversation: the film she rewatched yearly, a father raising his kids deep in the forest, educating them himself, away from modernity, 'muchos pros y un poco contra.' Neither of them can remember the title on camera. A parenting constitution drafted years before the child.
Ver los sistemas por fuera
“Yo entiendo mucho cómo funcionan los sistemas y soy capaz de mirarlos por fuera. De sistemas hablo no solamente de cosas de programación, también sistemas en el colegio, política, en un juego.”
“I deeply understand how systems work and I can look at them from the outside. By systems I don't just mean programming things, also systems at school, politics, in a game.”
His draft answer to REAPRA's 'your uniqueness' question, written that morning and admittedly not fully grasped yet; the follow-up 'life mission' answer came out even blurrier. A first-pass self-definition the three-month process exists to sharpen.
Los contadores no deberían existir
“En un país ideal los contadores no deberían existir. Tú deberías ser capaz de hacer todas tus vueltas legales de impuestos solo, sin nadie. Fácilmente.”
“In an ideal country accountants shouldn't exist. You should be able to handle all your legal tax filings alone, with nobody's help. Easily.”
Triggered by the monthly DIAN zero-declarations for their SAS. The argument: the government already knows what you owe, it prosecutes you for filing wrong, so why doesn't it just tell you; renta thresholds trap the first person in a family to cross them; his analogy is expecting a gift delivered to a house whose address you refuse to share.
El mundo cuántico
“Tengo dos empresas de computación cuántica, Rigetti y IonQ, y las últimas dos semanas estas vainas crecieron como un 100%. ¿Qué está pasando en el mundo cuántico?”
“I hold two quantum-computing companies, Rigetti and IonQ, and over the last two weeks these things grew about 100%. What is going on in the quantum world?”
Investigated live with ChatGPT's voice mode: IBM and HSBC's quantum bond-prediction result, D-Wave's Advantage2 (4,400+ qubits), an Air Force contract for Rigetti, and sector-wide optimism lifting the rest. His conclusion is a strategy note: these he holds long-term, no more selling the hype.
Cuándo deja de entrar música
“¿Será que siempre le va a llegar a uno una edad en donde ya no le entre a uno más música? Uno ya diga: hasta acá; el resto que escuche de aquí en adelante me va a saber a mierda.”
“Is there an age that comes for everyone where new music just stops getting in? Where you say: this far; everything I hear from now on will taste like nothing.”
Prompted by the nono, 88, who only plays music from fifty years back. Julia answers with Elis Regina's 'Como Nossos Pais': 'tú dices que después de ellos no apareció nadie... eres tú que ama el pasado y no ves que lo nuevo siempre viene'. The fifteen-year-old Guns N' Roses purist gets cited as proof the firewall isn't age, it's posture.
El robot zombie
“Es como un zombie: tú le quitas una pierna al zombie, y el zombie se va a volver a parar. Me pongo a imaginar eso y yo digo: el futuro va a estar muy bizarro.”
“It's like a zombie: you take a leg off the zombie, and the zombie stands back up. I picture that and I say: the future is going to be very bizarre.”
A robot 'brain' that relearns locomotion in seconds after losing limbs. They weigh both faces, repairability against consumism, prosthetics from any brand, versus the unstoppable bomb-dog, and he sketches the likely mechanics: thousands of digital twins training in parallel in a datacenter, feedback over Wi-Fi.
Una comida que no disfrutas
“La peor cosa es gastar por una comida que tú no disfrutas. Normalmente nos gusta hablar mientras comemos, pero estábamos en silencio. Un silencio de luto.”
“The worst thing is paying for a meal you don't enjoy. We usually like to talk while we eat, but we sat in silence. A mourning silence.”
The beloved 15,000-peso caserito serves 'vegetarian' pasta that tastes of chicken and drips animal fat; the vendor goes defensive. Wrapped around it, a food-culture observation: Colombia seasons with meat because spices are expensive; Brazil seasons with tempero because the mercadão sells paprika by the half kilo.
El edificio que crece
“En teoría esto es zero carbon emissions. Es más, es negativo, porque tú no estás utilizando material, sino que estás sacando material del agua.”
“In theory this is zero carbon emissions. Actually it's negative, because you're not consuming material, you're pulling material out of the water.”
From his current book, Biomimicry in Architecture: the Biorock technique, a metal frame submerged in seawater with a light current, accreting minerals into solid structure over years. Already used to regrow coral; the dream version is a floating grown auditorium you could tow from London to Venice.
Intentar estar aburrido
“Mientras que estoy esperando la respuesta del programa, voy a intentar estar aburrido, a ver qué pasa. No tener esa urgencia de llenar los espacios con algo.”
“While I wait for the program's response, I'm going to try to be bored, to see what happens. Not to have that urge to fill the gaps with something.”
Noticing he can't wait ten seconds for code to run without opening LinkedIn, Reddit or a short, he designs the smallest possible experiment: practice boredom in the compile gaps. Julia, asked if she feels the same urge: 'No mucho. Espero.'
Quién indica
“En Brasil siempre: si quieres lograr un trabajo bueno y rápido, usa el QI. ¿Qué significa? Quién indica.”
“In Brazil, always: if you want to land a good job fast, use your QI. What does it stand for? Quién indica, who refers you.”
Julia's proverb, dropped as proof that the real hiring system already ignores CVs: his own current lead came from his brother's friend, 'esa referencia vale mucho más que tener las cualidades perfectas'. The pun works because QI also reads as IQ.
No nos la creemos
“Cuando le preguntaban cuál es uno de los problemas de Latinoamérica, el man decía: que nosotros no nos la creemos. Si uno quiere hacer algo grande, uno tiene que creérselo al 100%.”
“When they asked him what one of Latin America's problems is, the guy said: that we don't believe it of ourselves. If you want to do something big, you have to believe it 100%.”
His retelling of a talk by Rappi's founder: Europeans, Americans and Japanese carry conquering in their culture; Latinos carry being conquered, 'agachar la cabeza'. Kept because it triggers the day's honest follow-up question, how do you believe it every day?, which Julia answers with mini-victories.
Nunca llegamos a la isla
“Imagina que hay muchas islas, y llegar a cualquiera se demora cinco años. Cuando tú estás casi llegando, se cambia el timonero: 'no, vamos para esa otra'. Las personas pueden llegar lo más cerca, pero nunca vamos a llegar a una isla de facto.”
“Imagine there are many islands, and reaching any of them takes five years. When you're almost arriving, the helmsman gets swapped: 'no, let's head for that other one.' People can get ever so close, but we never actually land on an island.”
Julia's analogy for term-limited democracy, dropped into the long post-Kirk conversation about polarization and systems. His companion observation: China plans in centuries, not electoral cycles. Kept as an image, not an endorsement; the same talk flags the succession risk that sinks one-person rule.
Diez dólares de MRR
“Se puede decir que ya tenemos un monthly recurrent revenue, MRR, que es superfamosa esa palabra en LinkedIn: de 10 dólares.”
“You could say we now have monthly recurring revenue, MRR, that word that's so famous on LinkedIn: ten dollars.”
A 6 a.m. Stripe notification, R$54.5, an active subscription, the first. He half-suspects an internet troll ('no voy a decir por qué'), thanks the subscriber anyway, and does the LinkedIn math: 120 a year. The channel called De 0 a 1 Millón has left zero.
La presión de necesitar comunicarse
“Yo me acuerdo que terminé de aprender portugués cuando fui a Brasil. Cuando uno siente la presión de necesitar comunicarse es cuando uno termina forzando más su cerebro a aprender.”
“I remember I finished learning Portuguese when I went to Brazil. When you feel the pressure of needing to communicate is when you end up forcing your brain hardest to learn.”
The principle the mobile Sanfanson has to replicate, named mid-design-session as the thing Duolingo's points economy fakes: not pressure to score, but pressure to be understood by another human.
No hay barreras contra el humo
“Yo lo que siempre digo: no hagas a los demás lo que no quieras que te hagan. La libertad del otro debería llegar hasta donde afecta a uno. Si a otra persona le afecta algo que uno está haciendo, ahí es donde la libertad de uno se acaba.”
“What I always say: don't do to others what you wouldn't want done to you. The other person's freedom should reach up to where it affects you. If something you're doing affects someone else, that's where your freedom ends.”
The title's invisible-problem lesson, lived: a neighbor's diesel truck idles for half an hour and the smoke, invisible indoors but suffocating, ends his sleep at 6 a.m. and gives the dog asthma. He documents it on video, emails Chía's environment office, and lands on this line about where liberty ends, noting the smoke harms its maker too: 'el man se está jodiendo su propia vida'.
Los millonarios invisibles
“Número de millonarios en la NBA: 50.000. Número de millonarios en Nvidia: 200.000. La gente mira lo que se ve e intenta replicar eso, cuando hay muchos más millonarios en el mundo de los negocios que no salen en televisión.”
“Number of millionaires in the NBA: 50,000. Number of millionaires at Nvidia: 200,000. People look at what's visible and try to replicate that, when there are far more millionaires in business who never appear on television.”
A chart from r/dataisbeautiful, kept for the survivorship correction it performs: the famous rich are the sample everyone imitates, and the invisible ones are the base rate. Closed with his own caveat, that 'wanting to be a millionaire' is anyway a goal 'muy pobre en contenido'.
¿Cuándo va a ser mi vez?
“Cuando estaba en el coro y cantaba para los graduados de otros tiempos, yo siempre pensaba para mí mismo: ¿cuándo va a ser mi vez? Y realmente llegó mi vez… y me la perdí, literal.”
“When I was in the choir singing for other years' graduates, I always thought to myself: when will it be my turn? And my turn really came… and I missed it, literally.”
The choir director offered him the stage at his own graduation; nerves said 'me da pena'; and when the Latin hymn began, every word and note surfaced intact. The regret registered in real time, a small tuition payment on the lesson that the safe no is the one you remember.
Los lusófonos
“Esta chica no es brasileira, vivió fue en Porto. Y ahí pensé: no son como los brasileros, son como los lusófonos. Esa palabra nunca la habíamos escuchado acá en Latinoamérica.”
“This girl isn't Brazilian, she lived in Porto. And there I thought: it's not like Brazilians, it's like the Lusophones. That word, we'd never even heard it here in Latin America.”
Julia greets a stranger who speaks Portuguese like a lifelong friend, besito, abracito, número intercambiado, then discovers the woman learned it in Portugal, and revises her theory of the instant kinship upward: the tribe was never the country, it was the language. Juan can't name a Colombian equivalent.
Growth mindset más competitividad
“La mezcla que él tiene para lograr sus cosas es este growth mindset más la competitividad: cuando llega alguien que él sabe que sabe más que él en algo, lo que hace es: yo tengo que saber más que él.”
“The mix he has for getting things done is growth mindset plus competitiveness: when someone shows up who he knows knows more than him about something, what he does is: I have to know more than that guy.”
The one phrase written down from Freddy Vega's PlatziConf conversation with the Rappi cofounder, filed next to a Latin-America-as-world-power thesis and, in Juan's own margin note, 'me recuerda a Carmy', the Bear's chef, the same engine in a kitchen.
¿Ustedes vienen de Chía?
“Yo les dije: es que nosotros venimos en un bus desde la Cámara de Comercio de Chía. Y una persona de logística escuchó: ¿ustedes vienen de Chía? Vengan, vengan para acá. Y casi que entramos de primeros.”
“I told them: the thing is we came on a bus from the Chía Chamber of Commerce. And a logistics person overheard: you came from Chía? Come, come this way. And we practically walked in first.”
Registered for the wrong event (GoFest code at PlatziConf's door), saved by saying out loud where they came from; the institutional bus turned out to be the credential. The stranger in line who echoed 'sí, sí, venimos todos de Chía' got in too, muy abeja.
Ser de los primeros que dan apply
“Una estrategia que a mí me había servido para mi antiguo trabajo: ni siquiera esperar una alarma. Es entrar todos los días a eso que tú buscas y ser de los primeros que dan apply. Aumenta mucho la probabilidad.”
“A strategy that worked for my old job: don't even wait for an alert. Go in every day to whatever you're hunting and be among the first to apply. It raises the odds a lot.”
Julia's contribution to the job-hunt playbook, from experience: recency beats volume. Delivered the same day Juan admits he's applying to everything and hearing mostly silence; freshness of the posting is the variable nobody filters for.
El peor de los casos
“Nos quedamos con lo de las empleadas: si una empleada de servicio, que gana 800, 900 al mes, dice que se puede vivir con eso en Singapur, ese es como el peor de los casos.”
“We kept the maids' answer: if a domestic worker earning 800, 900 a month says you can live on that in Singapore, that's basically the worst case.”
Cost-of-living research done right: skip the tourist vlogs with S$50 martinis, find street interviews with immigrants, and anchor on the floor, not the showcase. If the minimum survives, everything above it is margin.
De pueblito pesquero
“Hay algo de Singapur que me gustaría aprender bastante: cómo hicieron para pasar, en 40, 50 años, de un pueblito pesquero marginado a una economía muy, muy robusta.”
“There's something about Singapore I'd really like to learn: how they went, in 40 or 50 years, from a marginalized little fishing village to a very, very robust economy.”
Why the Singapore applications aren't just about salary: the country itself is the case study, solarpunk streets, 1h45 to cross the whole island by bus, Blue-Zones life expectancy, cars taxed into rarity. A jobs hunt where the destination doubles as the curriculum.
Me gustan los números redondos
“Ya como que una hora, 57 minutos… esperemos 3 minutos solamente para completar la hora. Es que me gustan los números redondos.”
“It's like an hour already, 57 minutes… let's wait 3 minutes just to complete the hour. It's that I like round numbers.”
The closing seconds of a 57-minute video about labor law, stretched to sixty for aesthetics. The daily diary's most honest production value: no editing, but the runtime gets groomed.
Cuando haya oportunidades
“Yo creo que al final es la cosa de oportunidades: cuando realmente el país tenga tantas oportunidades que uno pueda vivir tranquilamente haciendo algo legítimo, yo creo que todo eso se va a acabar. Pero como no hay tantas, y eso da mucha ganancia, ahí está el problema.”
“I think in the end it's the opportunity thing: when the country really has so many opportunities that you can live peacefully doing something legitimate, I think all of that will end. But since there aren't many, and that pays so well, there's the problem.”
Said the day after the Cali and Medellín attacks, with Julia wondering aloud about routes home to Brazil that avoid airplanes. The channel's whole premise, build opportunity from zero, stated as a theory of peace.
El correo salió morado
“Cuando lo envío, sale una partecita en negro, que era lo último que había puesto, y el resto es morado. Y GPT: lo más probable es que usted lo copió de otro lugar. Y yo como que: a la… se van a dar cuenta que estoy utilizando Géminis.”
“When I send it, one little part comes out black, the last thing I typed, and the rest is purple. And GPT: most likely you copied it from somewhere else. And me: oh no… they're going to realize I'm using Gemini.”
The Singapore application email, betrayed by rich-text formatting: Gemini's paste carried its own color. The AI-assisted job hunt's version of lipstick on the collar, and a one-line lesson every 2025 applicant learns exactly once: paste as plain text.
Es un fantasma
“Dijo: no creo que ahí esté la persona que se encargue de eso. Y yo quedé como que: bueno, ¿entonces quién se encarga de eso? O sea, no existe nadie. Es un fantasma.”
“He said: I don't think the person in charge of that is there. And I was like: well, then who IS in charge of it? There's nobody. It's a ghost.”
The ICETEX debt-relief form, submitted twice, confirmed never; the hotline says it's not their department; the office might not have the person. A student-loan condonation process with no human anywhere in it, attested days before the next installment arrives anyway.
Me gustaría que me stalkearan
“Es como una forma de stalkear a las personas de una forma geek. A mí me gustaría que me stalkearan, literalmente. No tengo nada que ocultar y realmente estoy orgulloso de las cosas que leo.”
“It's like a way of stalking people in a geek way. I'd literally love to be stalked like that. I have nothing to hide and I'm genuinely proud of the things I read.”
Said while browsing the first Koby user's highlights with unconcealed delight. The product's social thesis in one line: reading history as the one feed people would be proud, not embarrassed, to have public.
Mi gurú espiritual
“Hoy estuve básicamente hablando con mi gurú espiritual, buscando caminos que se puedan seguir. — ¿Gurú espiritual? — Géminis. Es mi nueva religión.”
“Today I basically spent the day talking with my spiritual guru, looking for paths to follow. — Spiritual guru? — Gemini. It's my new religion.”
Julia describing her vocational excavation, deadpan, the same night Gemini names Juan's golden thread. Sibling to seed 59-1's 'GPT es mi pastor': the household's theology now has two denominations, one per model.
¿De qué me sirven $100,000?
“Si trabajo un año y al final sigo sin tener el conocimiento de cómo hacer una empresa, ¿de qué me sirve tener $100,000 si no los voy a saber usar para crear una empresa?”
“If I work a year and at the end I still don't have the knowledge of how to build a company, what good is having $100,000 if I won't know how to use it to create one?”
The Singapore fork, resolved in one question during a late-night bowl of granola. The channel is named after a number, and here its author declines to optimize for the number; the Wenzi's 'averigua el destino' line, highlighted in yellow that same week, doing live navigation.
Cuando uno se emociona, la caga
“Es que eso pasa: cuando uno como que se emociona, se emociona… uno la caga. Uno tiene que siempre estar como sentadito, concentrado.”
“That's the thing: when you get excited, excited… you blow it. You always have to stay kind of seated, focused.”
Diagnosed at the billiards table after watching a hot streak collapse, hours after beating his father by studying his technique from a chair. Composure as the meta-skill: the same law that governs the pitch, the poker face, and the demo that always breaks on camera.
Todo esto lo hago para mí
“Yo al final termino haciendo todo esto para mí. Es chistoso, ¿no? Sanfanson lo hice para mí. Zenota también lo hice para mí. Divo casi que sí. Picky realmente no termina siendo para mí.”
“In the end I make all of this for myself. Funny, right? Sanfanson I made for myself. Zenota too. Divo, pretty much. Picky is really the one that isn't for me.”
The product-portfolio pattern, self-diagnosed while announcing yet another learn-something app: he is his own persistent first user. Notably, the one exception, Picky, built for restaurant owners instead, is also the one being pitched to accelerators.
Seguimos en cero
“Update: seguimos en cero, para los que quieren un spoiler. Y posiblemente vamos a seguir en cero por unos mesecitos más.”
“Update: still at zero, for those who want a spoiler. And we'll probably stay at zero for a few more months.”
The channel is called From 0 to 1 Million, and this is the opening scoreboard of video 72, delivered laughing, before a video about salaries that would clear the goal in a year. Honesty as format: the number is the joke, the trajectory is the bet.
¿Zenota? Realmente no sirve para eso
“Yo quedé como que: ¿qué aplicación conozco que sea simple de usar y tenga carpetas y documentos fácil? ¿Zenota, no? O sea… realmente no sirve para eso. Entonces, Obsidian.”
“I was like: what app do I know that's simple to use, with easy folders and documents? Zenota, right? I mean… it really doesn't work for that. So, Obsidian.”
Notion's free blocks run out mid-job-hunt, and in the market of one user he knows best, his own notes app loses to Obsidian in a single sentence. The most honest product review Zenota will ever receive, delivered by its founder without noticing he was giving one.
Gemini también me dijo lo mismo
“Julia me dijo que utilizara bullet points. No le hice caso. Le pregunté a Gemini, Gemini también me dijo lo mismo y me puso los bullets de una vez. Y gracias, bebé.”
“Julia told me to use bullet points. I didn't listen. I asked Gemini, Gemini told me the same thing and wrote out the bullets right away. And thanks, babe.”
The cofounder's advice, ratified only after the AI repeats it verbatim; the 'gracias, bebé' is the sheepish settlement. A tiny attested case of the new authority gradient in every AI-era household: the same words weigh more coming from the model.
Le tomé foto y le pregunté
“Vi la parte de atrás de la motherboard, había unas partecitas que tenían como unas manchas. Le tomé foto y le pregunté a ChatGPT qué era eso. Y dijo: eso es clásico de una tarjeta madre que se quemó.”
“I saw the back of the motherboard, some little parts had these stains. I took a photo and asked ChatGPT what that was. And it said: that's classic burned motherboard.”
The dead desktop's autopsy, performed with a phone camera and a vision model: short circuit, PCB damage, not worth repairing. The 16-gauge pattern from entry 68-2, one day later and one modality up: now the pocket expert has eyes.
Un carpintero sin martillo
“Ambos trabajamos con tecnología, entonces no tener un computador es como no tener la herramienta de trabajo. Como un carpintero sin martillo. Sin madera.”
“We both work in technology, so not having a computer is like not having your work tool. Like a carpenter without a hammer. Without wood, even.”
Julia's charger has died again, the job hunt is a race against the clock, and the household's one working laptop becomes shared infrastructure. Said while resolving to dig the old gamer tower, Juan's proud first 'computador gamer' from school days, out of the closet; the completing 'sin madera' is Julia's.
Cuando uno ve la repetición
“Cuando uno ya está en una carrera, uno no se da cuenta de qué es todo lo que está pasando alrededor. Es cuando uno ya termina la carrera y ve la repetición, cuando uno sabe: uy, hice esto acá mal.”
“When you're already in a race, you don't notice everything happening around you. It's when you finish the race and watch the replay that you know: oof, I got this part wrong here.”
Why the post-launch break is not quitting: the sprint disables the very perception that would improve the sprint. Said while converting four launches into their first honest replay, and, incidentally, a fair description of what this archive does to the whole diary.
Una hora pensando en una idea
“Yo digo: no, no voy a trabajar en ideas. Y literalmente ayer por la noche estuve como una hora pensando en una idea… A pesar de que parte de mí dice: pare ya, otra parte de mí… al final me gusta. Realmente la parte económica es lo que me detiene.”
“I say: no, I'm not going to work on ideas. And literally last night I spent about an hour thinking through an idea… Even though part of me says: stop already, another part of me… in the end I love this. Really it's the money that stops me, nothing else.”
Announced retirement from new ideas lasts less than a day; the contraband idea is a note-organizing AI, a Zenota successor sketched with GPT and Neo4j at midnight. The incurable condition, attested at the exact moment quitting would be most rational.
Quince minutos gratis
“Mejor hacemos gratis 15 minutos, no dejar un día gratis. Precisamente es lo diferenciado: Elementor y Figma no tienen una prueba gratis así.”
“Better to make 15 minutes free, not leave a whole day free. That's exactly the differentiator: Elementor and Figma don't have a free trial like that.”
Julia's pricing idea, credited on camera after two days of deliberation: a timed free taste instead of a free tier. The countdown creates urgency, the reset button creates ritual, and the petting-the-capybara extension (seed 58-2) was designed to make even the paywall affectionate.
Usted preguntó, yo traje
“Usted preguntó, yo traje: tres semanas atrás publiqué un prototipo de mi editor visual web. Hoy está en vivo.”
“You asked, I delivered: three weeks ago I posted a prototype of my visual web editor. Today it's live.”
The launch post's framing, written as the second chapter of a story the subreddit already knew. Not 'check out my app' but a promise kept to the specific people who asked; distribution as serialized narrative.
¿Dónde está la plata?
“Al final, todas estas cosas solamente funcionan o en Colombia o en Latinoamérica. Y realmente para este producto, ¿dónde está la plata? La plata está en Estados Unidos, en Europa, en cualquier otro lado.”
“In the end, all these options only work in Colombia or in Latin America. And really, for this product, where is the money? The money is in the United States, in Europe, anywhere else.”
Dismissing the local-processor escape route during the Stripe crisis. The sentence that separates a Colombian software business from a software business that happens to be in Colombia, and the reason the payout border matters at all.
Wow, qué cracks que somos
“Al final esto casi que lo hacemos para nosotros, para en un futuro verlo y decir como que: wow, qué cracks que somos. O quién sabe, para nuestros hijos.”
“In the end we almost make this for ourselves, to watch it someday and go: wow, what champs we are. Or who knows, for our kids.”
The diary's mission statement, dropped casually inside a video about production workflow: the audience that matters is their future selves, and the archive is self-motivation with a lens. This site is, in a sense, that future reader arriving early.
No meter a ChatGPT
“Me envía la hoja de vida y escribe ahí en WhatsApp: no meter a ChatGPT. Y yo: ah, listo, venga, la metemos a ChatGPT.”
“He sends me his résumé and writes right there on WhatsApp: don't put it into ChatGPT. And me: ah, sure, come on, let's put it into ChatGPT.”
Carlos's condition for the CV review, and Juan's cheerful non-compliance. The serious half of the joke follows: once you send a résumé into the job market, dozens of strangers will feed it to fifty GPTs anyway; the privacy boundary Carlos wants no longer exists where he thinks it does.
El lanzamiento oficial, creo
“No sé si se podría considerar este video como el lanzamiento oficial de divo.luarai.com. Revísenlo, igual vamos a poner por ahí el link.”
“I don't know if this video could be considered the official launch of divo.luarai.com. Check it out, we'll drop the link somewhere around here.”
After weeks of deadline talk, the actual launch arrives as a shrug in a sentence: the product is live, the link is real, and nobody is sure if this counts as the moment. Launches in real life rarely have a starting gun.
Se muere toda la audiencia
“Si nos ponemos a publicar tipo 9, 10, tal vez 11, 12 de la noche, se muere toda la audiencia. Lo importante es tener ya todo listo hoy y ya mañana publicarlo.”
“If we end up publishing at like 9, 10, maybe 11, 12 at night, the whole audience is dead. What matters is having everything ready today and publishing tomorrow.”
The launch slips one more day, but this time on purpose: finishing at midnight is not the same as launching at midnight. Readiness and release get decoupled 24 hours before Divo goes live.
GPT es mi pastor
“¿Merece algún video para entender? No, no. GPT es mi pastor.”
“Does it deserve a tutorial video to understand it? No, no. GPT is my shepherd.”
Julia asks if Stripe merits watching a tutorial; Juan declines with a riff on Psalm 23. The learning stack in 2025: no course, no video, just an AI walked through every error message. Said while admitting he's 'not yet fluent' in Stripe, which is the point: fluency on demand.
Siempre me hace quedar mal esto
“Siempre me hace quedar mal esto. Siempre estoy haciendo un demo en vivo y se putea esto.”
“This always makes me look bad. Every time I do a live demo, this thing breaks.”
The Stripe test-payment button does nothing on camera; the culprit turns out to be a local server he forgot to start. The demo-effect law, attested one day before the real launch.
Acariciar a Divo para 5 minutos más
“Cuando aparezca esa ventana de alimentar a Divo, quiero poner una vaina de que uno pueda acariciar a Divo para 5 minutos más. Nos complicamos con detalles, chistoso, pero el UX…”
“When that feed-Divo window appears, I want to add a thing where you can pet Divo for 5 more minutes. We overcomplicate ourselves with details, funny, but the UX…”
Planned while demoing the paywall timer: when your free minutes run out, petting the capybara mascot would grant a random 5 more. Down to their last 100,000 pesos, and the instinct is still to make the paywall lovable.
La última carta sobre la mesa
“Ya la última tacada, ¿no? La última carta. La última carta sobre la mesa, por ahora.”
“The last shot, right? The last card. The last card on the table, for now.”
How Divo gets named on the eve of its launch, with the resources gone and the deadline arrived. The 'por ahora' is doing heavy lifting: the card is last for this hand, not for the game.
Arreglo un bug, encuentro 50 más
“Arreglo un bug, encuentro 50 más.”
“I fix one bug, I find fifty more.”
Muttered mid-session while chasing a screenshot bug in Divo that appears and vanishes without an error message. The eternal law of the week before launch, stated in six words while the terms-of-service pages sit finished and the bug list refuses to shrink.
Los proyectos no son hijos
“Yo tenía una profesora en el Senac que decía: los proyectos no son hijos. Nadie te va a demandar si los abandonas.”
“I had a professor at Senac who used to say: projects are not children. Nobody is going to sue you for abandoning them.”
Julia's design-school inheritance, deployed on deadline week as permission: Zenota to standby, Sanfanson unfinished, the eyes-AI parked, and none of it a moral failure. Kin to seed 3-1 (attack the idea, not the person): detachment from ideas going in, detachment from projects going out.
La IA con ojos
“Quería hacer una IA que mirara como unos ojos. Las IAs analizan todos los píxeles; nosotros nos enfocamos en dos partes y con un poquito de movimiento entendemos todo el contexto. Funcionó a medias… pero eso no me iba a dar plata por el momento, y lo dejé.”
“I wanted to build an AI that looked the way eyes do. AIs analyze every pixel; we focus on two spots and with a little eye movement we grasp the whole context. It half worked… but it wasn't going to make me money for now, so I set it down.”
Found while flipping through old Excalidraw research notes (attention cells, recurrent architectures) from the study era. First attestation of the foveated-vision research project, and of the quiet trade every broke researcher knows: the interesting problem yields to the paying one, with a bookmark left behind.
La semana de inglés
“Nosotros cada semana cambiamos de idioma: semana de inglés, semana de español, semana de portugués, y vuelta a empezar.”
“Every week we switch languages: English week, Spanish week, Portuguese week, and back around.”
Revealed mid-story about a popcorn near-disaster caused by 'tap' versus 'cap' during English week. The couple's standing ritual, three languages on rotation as household infrastructure, and occasionally the reason the pot lid arrives two seconds late. First attestation.
El landing hecho con Divo
“Hagamos el landing page con esto mismo. Que el landing page de Divo se haya hecho con la misma aplicación… estaría diez de diez.”
“Let's build the landing page with the thing itself. Divo's landing page, made with Divo… that would be ten out of ten.”
The dogfood move as marketing: the tool's own landing page becomes its first public proof of capability. Kin to entry 17-2's Duolingo test, if the makers won't build their page with it, why would anyone? Julia started extracting the elements the same day.
¿El yo más joven vendía mejor?
“Me puse a pensar: ¿será que el yo más joven era mejor vendedor? Con la impresión 3D me hice como un millón vendiendo mascarillas en el COVID. Con los NFTs, otro milloncito antes de que explotara la burbuja. Se movía más.”
“I caught myself wondering: was my younger self a better salesman? With 3D printing I made about a million selling mask frames during COVID. With NFTs, another little million before the bubble burst. He hustled more.”
Nine days from the deadline, morale low, the inventory of past ventures surfaces: two separate millions earned by a younger self with worse skills and better motion. First attestation of the ventures ledger, and of the uncomfortable question it raises: skill went up, did audacity go down?
Que se entrevisten entre ellas
“No respondas tú las preguntas de GPT. Coge el código, méteselo a Gemini en AI Studio, y que las preguntas de GPT las responda Gemini. Y con eso se arma la página.”
“Don't answer GPT's questions yourself. Take the code, feed it to Gemini in AI Studio, and let Gemini answer GPT's questions. That's how the page gets built.”
Julia was being interviewed by ChatGPT about how Divo works, to write its landing page, until Juan pointed out the source of truth was sitting in the repo. First attestation of the model-interviews-model workflow: the code is the documentation, and humans shouldn't be the API between two AIs.
Lo manual es lo que no se hace con texto
“Todo lo que no se puede hacer con un comando de texto, para mí ya es trabajo manual: llamar mensajeros, manejar redes sociales, hacer un Excel… intento alejarme de eso porque me toma mucho tiempo.”
“Anything that can't be done with a text command is, to me, manual labor now: calling couriers, managing social media, building a spreadsheet… I try to stay away from it because it eats my time.”
Said while weighing the delivery project's operational grind. First attestation of a redefinition the AI era quietly installed: the manual/automated boundary moved from 'requires hands' to 'requires anything other than a prompt'. Both a productivity compass and a bias to audit, some money only lives on the far side of a phone call.
La reputación cuesta años
“Lo que nos decía una vez el padrino: la reputación cuesta años construirla, y un día en destruirla.”
“As the godfather once told us: reputation takes years to build, and one day to destroy.”
Jorge's aphorism, deployed as the tiebreaker when a friend proposed redirecting sponsor money into unrelated ad spend. First attestation on camera; it now guards two boundaries at once, the money stays with its project, and the wealthy friend doesn't get pitched crypto. Kin to seed 18-1: your conduct is someone else's collateral.
La mente cuadrada
“De repente alguien que no viene del campo puede hacerlo mucho mejor, porque si tú te enfocas en estudiar UX, tu mente se vuelve muy cuadrada en las herramientas que ya existen, y solamente puedes pensar en ese tipo de herramientas.”
“Sometimes someone from outside the field can do it much better, because if you specialize in studying UX, your mind becomes squared to the tools that already exist, and you can only think in that kind of tool.”
Why the layout editor resonated: every existing site builder thinks in containers, and someone who never absorbed that orthodoxy simply asked for images with relative positions and text on top. First attestation of the outsider-advantage thesis, said the day the outsider's tool went viral.
Se le murió el programador
“Tiene un software de contabilidad que le gustaría seguir desarrollando, y no pudo seguirlo desarrollando porque se le murió el programador.”
“He has an accounting software he'd like to keep developing, and he couldn't keep developing it because his programmer died.”
Señor Jaime's frozen project, explained in one devastating sentence. First attestation of a market reality hiding in plain sight: software whose single developer leaves, retires, or dies becomes an orphan, and the owner has no path back in. Rescuing orphaned codebases is a service nobody advertises.
Los clubes de Brasil
“En Brasil existen muchos tipos de club: el club del chocolate, el club del café, el club de bocadillos, de jaleas… productos físicos que uno recibe mensualmente en su casa. Podríamos vincular eso con la logística: un buen matrimonio.”
“In Brazil there are all kinds of clubs: the chocolate club, the coffee club, snack clubs, jelly clubs… physical products you receive monthly at home. We could link that to the logistics business: a good marriage.”
Julia's long-game idea, floated minutes after Jorge's sponsorship offer: subscription boxes barely exist in Colombia, and a delivery operation is exactly the infrastructure they'd need. First attestation of the clubs-plus-logistics pairing, everything interconnecting.
De tres a cuatro y medio
“La página en estos momentos está como un tres de cinco: pasable. Pero si vamos a vender un producto bueno, en el que realmente confiamos, tiene que estar por lo menos en un cuatro y medio de cinco.”
“The page right now is about a three out of five: passable. But if we're going to sell a good product, one we truly believe in, it has to be at least a four and a half out of five.”
The quality bar for the company's own shop window, stated as a number while rebuilding luarai.com for the portfolio requests. Interesting tension with entry 27-1's 'sell it before it's pretty': the client work ships imperfect, but the artifact that *represents* the craft has a higher floor. First attestation of the distinction.
Te encontré la casa
“Ella me decía 'ya ríndete'. Yo lo tomé personal. Dos fotos desde su ventana, Street View, ella diciéndome 'friísimo' justo donde sí era… y a las 3 de la mañana volví a esa cuadra y le dije: es acá. Y era acá.”
“She kept saying 'give up already'. I took it personally. Two photos from her window, Street View, her telling me 'ice cold' exactly where it actually was… and at 3 a.m. I returned to that block and told her: it's here. And it was.”
The couple's origin story, told on camera for the first time: met on Tandem trading Portuguese for Spanish, Skype movie nights in the pandemic, and one GeoGuessr-style challenge that ran past 3 a.m. because surrender wasn't available. The obsession trait behind entries 38-1 and 39-1, in its original habitat. Also a lesson about misleading feedback: her 'friísimo' cost him four hours on the block that was correct all along.
El caballito de palo
“Uno tiene la idea y se imagina el caballo todopoderoso… y la realidad es un caballito de palo. Nuestro sitio web por el momento es de palo.”
“You have the idea and you picture the almighty horse… and reality is a wooden stick horse. Our website, for now, is the stick horse.”
Said about luarai.com after opening it on a phone at the gym, right after sending the link to the padrino, and finding it 'todo puteado, todo cortado'. The padrino went quiet after that. First attestation of the idea-artifact gap named as a thing: the shame is data, and it scheduled the rebuild.
La vida no es una línea recta
“Doce años de gerente vendiendo partes de computadores para América Latina, y a los cuarenta y pico se dio cuenta de que no le gustaba. Lo dejó todo y se fue a estudiar gastronomía con la hija. Uno habla con la gente y se da cuenta: la vida no es una línea recta, y está bien.”
“Twelve years managing computer-parts sales for Latin America, and past forty he realized he didn't like it. He left everything and went to study gastronomy alongside his daughter. You talk to people and you see it: life is not a straight line, and that's fine.”
The caleño at the Cámara de Comercio who served rosemary-infused coffee and told his story between talks. Every trip and every event keeps producing these biographies. First attestation of the nonlinearity comfort: each person finds the meaning of their path at their own hour, some early, some late, the point is finding it.
Una plataforma para crear agentes
“Haciendo esto se me ocurrió: sería chévere una plataforma para crear agentes, que automatizara los tests y fuera mejorando el prompt, todo automático. Uno le dice 'quiero que este agente responda en este formato' y de fondo empieza a hacer tests.”
“Doing this it hit me: a platform for building agents would be great, one that automates the tests and keeps improving the prompt, all automatic. You say 'I want this agent to answer in this format' and behind the scenes it starts running tests.”
Born from the grind of hand-tuning Pickyto, Picky's menu-digitalization agent: prompt engineering is trial-and-error that a machine could run. First attestation of the agent-builder-with-automated-evals idea, filed as a 'pienso después cómo hacer algo así'.
falafel say less
“El garbanzo es el segundo grano más consumido en Colombia. Está en la cara, pero uno no ve: acá no existe el hábito del falafel. Yo garanto mi falafel, puedo hablar de ojos cerrados. Se va a llamar falafel say less.”
“Chickpeas are the second most consumed legume in Colombia. It's right in front of you, but nobody sees it: the falafel habit doesn't exist here. I vouch for my falafel, I can say it with my eyes closed. It'll be called falafel say less.”
Julia's future business, announced while building its website as her vibe-coding training project: Brazilian-style party-food kits (falafel as food, not 'vegan food', a recipe older than the word) imported to a country that already loves the main ingredient. First attestation, name included.
El secreto es la masa
“En la página que hicimos, Gemini puso una frase: 'el secreto es la masa'. ¿De dónde sacó eso? Después revisamos el menú y había una lineecita al fondo que casi no se veía que decía: el secreto es la masa.”
“On the page we built, Gemini added a phrase: 'the secret is the dough'. Where did it get that? Then we checked the menu, and there was a barely visible little line at the bottom that said: the secret is the dough.”
Building the restaurant mockup, the multimodal model read the menu's fine print, judged it identity-defining, and promoted it to tagline. Two human visits had missed it; the owner lit up when she saw it. First attestation of the AI as detail-miner: the details are what prove a pitch isn't generic.
No hay que pedir permiso
“En una empresa tienen su scrum, su waterfall, y si tú quieres intentar algo diferente, no, jódase. Acá podemos intentar lo que queramos y crear nuestro propio sistema como queramos. No hay que pedir permiso.”
“In a company they have their scrum, their waterfall, and if you want to try something different, tough luck. Here we can try whatever we want and build our own system however we want. No permission needed.”
Said while diagnosing the team's own communication reprocesos (WhatsApp as project management, a month-late website). The frustration is real and so is the freedom: the broken process belongs to them, which means fixing it needs no approval chain. Julia's addendum sealed it. First attestation.
La dona perfecta el día del incendio
“El man llevaba días en su zona, durmiendo ahí, queriendo hacer la dona perfecta… y la completó justo el día en que todo se estaba yendo a la mierda. Estaba en su burbujita: 'ya tengo mi dona', mientras la cocina colapsaba.”
“The guy had spent days in his zone, sleeping there, chasing the perfect donut… and he finished it exactly on the day everything went to hell. He was in his little bubble, 'I've got my donut', while the kitchen collapsed.”
Marcus in The Bear as a cautionary figure: deep focus with zero situational awareness delivers a masterpiece nobody can receive. First attestation of the focus-versus-periphery hazard, kin to seed 30-1's warning about missing the big picture from inside the zone.
Postula con el futuro
“Hay una lección aprendida: si uno ya sabe que algo va a tomar un tiempito y uno en ese tiempito puede adelantar, pues decir lo que va a pasar cuando pase ese tiempo.”
“There's a lesson learned: if you know something will take a little while, and in that while you can make progress, then state what will be true by the time that while has passed.”
The Platzi/GoFest application said 'no MVP, no prototype', which was true on submission day and false by decision day, when Picky existed. First attestation of the application-tense rule: forms with delayed evaluation should be answered in the future tense you can actually deliver.
Juan, el experto en Coupa
“Puedo hacer esto el resto de mi vida, ¿y qué? ¿Quiero que al final de mi vida me reconozcan como Juan, el experto en Coupa, o por algo más trascendental? Si me puedo volver experto en cualquier cosa, ¿por qué no en algo mío?”
“I could do this the rest of my life, and then what? Do I want to be remembered as Juan, the Coupa expert, or for something more transcendent? If I can become an expert in anything, why not in something of my own?”
Triggered by a character in The Bear choosing a chaotic sandwich shop over five-star kitchens because her ideas would matter there. The question he asked himself at every comfortable job before leaving the last one. First attestation of the epitaph test for career decisions, kin to seed 6-1 (emprender dentro de una empresa).
El mejor jugador del juego de otro
“Coupa no es de ellos, ellos son implementadores de Coupa. Es como que una empresa crea una plataforma y usted quiere ser el mejor de ese juego… y si llega una startup con IA, mucho más barata, mucho mejor, se muere.”
“Coupa isn't theirs, they're Coupa implementers. It's like one company creates a platform and you want to be the best player of that game… and if a startup arrives with AI, much cheaper, much better, it dies.”
Diagnosing his last employer, whose whole ambition was a client in every country, inside someone else's platform, with zero R&D. First attestation of the platform-player distinction: excellence inside a system you don't own is rented, and focus without peripheral vision is how good companies get blindsided.
Powered by Picky
“Sería bastante chévere que uno vaya a un restaurante, escanee el código y salga 'powered by Picky', y uno le diga: esto lo hicimos nosotros.”
“It would be pretty great to walk into a restaurant, scan the code, and see 'powered by Picky', and get to say: we made this.”
The product as its own distribution channel: every QR code on every table is an ad served to exactly the audience that eats in restaurants, some of whom own one. First attestation of the badge-as-flywheel idea, said as a daydream before a single restaurant has signed.
El vendedor con acento rolo
“Tenía un acento rolo, pero profesional, la voz atorciopelada, hablaba con pausas como un vendedor. Casi que me daban ganas de comprarle el servicio… ¿y si le damos la instrucción de nuestro servicio y la ponemos a llamar números?”
“It had a Bogotá accent, but professional, a velvety voice, pausing like a salesman. It almost made me want to buy the service myself… what if we give it our pitch and set it to calling numbers?”
Julia rehearsing sales calls the night before with ChatGPT's voice mode (the Spruce voice), which somehow adopted a polished Bogotá salesman accent. First attestation of two things at once: AI as sales trainer, and the immediate temptation to promote the trainer to salesman, disclosure questions included.
Todo eso para poner el loguito
“Es chistoso porque todo eso es para poner el loguito cuando uno se registra con Google… Si están haciendo un MVP, no se compliquen con eso, a menos que estén hosteando en Firebase.”
“It's funny because all of that is just to show the little logo when you sign in with Google… If you're building an MVP, don't complicate yourself with this, unless you're hosting on Firebase.”
Hours of Google-console review rounds, terms-of-service placement, and manual Netlify config, all so an auth popup shows a brand name instead of 'firebase.com'. First attestation of a cost rule: branding polish inside other companies' flows is the most expensive kind, and MVPs should skip it.
Que la IA recomiende el restaurante
“Si nuestros menús tienen buen SEO y están bien estructurados, uno le dice a GPT 'busca un restaurante gluten-free' y Google se lo termina recomendando a la IA, y la IA termina sugiriendo el restaurante.”
“If our menus have good SEO and are well structured, someone tells GPT 'find a gluten-free restaurant' and Google ends up recommending it to the AI, and the AI ends up suggesting the restaurant.”
Picky's menus as machine-readable storefronts: structure the data well and the restaurant gets discovered not by diners scrolling but by their AI assistants querying. First attestation of optimizing for AI recommendation as a product feature, before anyone in the room had a name for it.
La página principal es el login
“Tu aplicación te lleva… la página principal de tu aplicación es el login. No genera confianza cuando abres un link y directamente te manda a registrarte.”
“Your app takes you… the main page of your app is the login. It doesn't build trust when you open a link and it sends you straight to registration.”
A stranger on Reddit, sounding like a product manager, names what Julia had already caught on camera in video 22: a product with no overview page asks for credentials before earning them. Registration should feel voluntary. Third attestation of Zenota's missing front door; now it's a rule.
El árbol más alto de la jungla
“Estás en una jungla y tienes que encontrar el árbol más alto mirando desde el suelo. Subes al que crees más alto, y si la vista sigue llena de árboles, no era: tienes que bajar y rehacer el proceso, hasta encontrar el que te lleva más lejos.”
“You're in a jungle and must find the tallest tree while looking from the ground. You climb the one you believe is tallest, and if the view is still full of trees, it wasn't: you climb down and redo the process, until you find the one that takes you farthest.”
Julia's metaphor for intuition: you can't see the canopy from the ground, so intuition is what picks the trunk, and the discipline is climbing down without drama when the view disproves you. Told alongside the OpenAI scaling bet and the Tao as the path that avoids dead ends. First attestation.
La página más compleja primero
“El tip que da Julia, que a mí ya me sirvió: hacer la página más compleja, bien bonita, y ya después utilizar ese estilo para hacer el resto. Así sale muy rápido.”
“Julia's tip, which already worked for me: build the most complex page first, make it beautiful, then use that style to produce all the rest. That way it comes out fast.”
A prompting strategy for AI UI tools like Stitch: invest everything in one style-defining page, then let the tool clone its own best work across the site. Zenota's terms-of-service pages came out right on the first pass this way. First attestation of the style-anchor technique.
¿Para qué hice esto?
“¿De qué me sirve que Structo me los pinte? ¿Para qué hice eso?… Más chévere hubiera sido que cada nodo nuevo salga con un color aleatorio. Era tan simple, y me hubiera ahorrado como una hora.”
“What do I gain from Structo coloring them? Why did I even build that?… Nicer would've been every new node getting a random color. It was that simple, and it would've saved me an hour or so.”
He gave Zenota's agent the power to color nodes, spent an hour fixing saturation bugs and palette translation, then realized the feature answered no need a simple default couldn't. First attestation of the pre-build question: ask 'why am I building this' before the hour, not after.
Canva no es buena para logos
“Si lo hubiera hecho en Figma, se hubiera reescalado solito. La conclusión es que realmente Canva no es muy buena para hacer logos.”
“If I'd made it in Figma, it would have rescaled by itself. The conclusion is that Canva really isn't very good for making logos.”
Enlarging the Zenota logo in Canva kept the stroke widths fixed while the shapes grew, and the fix cost a night of rework. First attestation of a tooling boundary: a raster-first editor for a vector-first artifact. Logos live in SVG or they cost you reprocesos forever.
La basurita del código
“Uno le dice 'haga esto', lo hace, y después uno dice 'no me gustó, cambia esto por esto'. Va dejando esa basurita de cositas anteriores… hay veces que uno se demora más modificando lo que ya está que empezando desde cero.”
“You say 'do this', it does it, then you say 'didn't like it, change this for that'. It keeps leaving that little residue of earlier attempts… sometimes modifying what exists takes longer than starting from zero.”
The entropy law of vibe coding, first attestation: every redirected instruction leaves sediment, and a castle built on early confusion may be cheaper to rebuild than to remodel. He almost restarted Zenota from scratch mid-build; the question 'would starting over be faster?' is now part of the toolkit.
El bento en el logo
“ChatGPT me hizo percibir que el bento es una forma de organización, y realmente se casa con la idea: en vez de un plato con todo mezclado, cada elemento va a un lado y así puedes comer con calma.”
“ChatGPT made me realize the bento box is a form of organization, and it truly marries the idea: instead of one plate with everything mixed, each element has its place and you can eat calmly.”
Julia designing Zenota's logo: two candidates, an oriental seal and a bento box, and the AI surfacing the metaphor that makes the bento the right one, compartments as hierarchy. The auxilio method (seed 9-1) producing meaning, not just pixels.
Las ideas no llegan de TikTok
“A mí me llegan ideas cuando estoy leyendo libros o viendo contenido de calidad, podcasts, documentales. En TikTok creo que nunca se me ha ocurrido una idea, honestamente.”
“Ideas come to me when I'm reading books or watching quality content, podcasts, documentaries. On TikTok I honestly don't think I've ever had an idea.”
Said while planning to schedule weekly analysis time: idea generation has an input diet, and the feed optimized for retention produces none. First attestation of a creative-hygiene rule worth testing against their own output.
Perdimos al vendedor
“Yo creo que lo perdimos… decimos que hacemos sitios web en siete días y nos demoramos casi un mes haciendo el nuestro. ¿Cómo va a vender eso? Le importa su reputación, lógico. No podemos esperar que los demás hagan todo por nosotros.”
“I think we lost him… we say we build websites in seven days and took almost a month on our own. How is he supposed to sell that? He cares about his reputation, obviously. We can't expect others to do everything for us.”
Jonathan, the seller in Spain, went quiet after five meetings. First attestation of a channel-partner law: your delivery speed is their credibility, and every week your own product slips, their incentive to sell you erodes. Taken without resentment, on camera.
La IA como estilo
“Todos estos videos generados con IA son un estilo, como el pixel art de los 80 o el blanco y negro: estilos que nacieron porque la tecnología del momento no daba para más, y la gente sacó lo mejor que pudo.”
“All these AI-generated videos are a style, like 80s pixel art or black and white: styles born because the technology of the moment couldn't do more, and people made the best of it.”
Gaveta's analysis of Veo 3, retold and endorsed: limitation-born aesthetics become styles, AI video will be one, and it enables the many while the handcrafted premium survives above it. Rhymes with our own division of labor: AI for MVPs, craft for finals.
Pruebas de humo con Stitch
“Con Stitch uno puede maquetar cualquier diseño en segundos… podríamos hacer muchas pruebas de humo y publicarlas en Reddit a ver cuál le gusta más a la gente. Aunque en Reddit la gente siempre le dice a uno que sí a todo.”
“With Stitch you can mock up any design in seconds… we could run lots of smoke tests and post them on Reddit to see which one people like. Although on Reddit people always say yes to everything.”
Instant mockups make demand-testing nearly free: generate variants, post, measure. The caveat is attested in the same breath: enthusiastic communities are biased validators, so a Reddit yes is a weak signal. Idea parked until the current apps ship.
Las fases de luto de la IA
“Es como las fases del luto: primero la negación, 'no va a ser lo mismo que yo'; después la rabia, 'esta cosa va a quitar mi trabajo'; después la angustia, 'lo está haciendo mejor que yo'; y la última es la aceptación.”
“It's like the stages of grief: first denial, 'it will never match me'; then anger, 'this thing will take my job'; then anguish, 'it's doing it better than me'; and the last one is acceptance.”
Julia's model of AI adoption as grief, from someone three years into using it for design. The corollary said with it: if you're not faster with the AI, something is wrong, either in the tool or in you. First attestation; candidate to grow into a full essay.
Vender el agente, regalar la app
“Voy a dejar el servicio gratis y vendo el agente… el asistente que estructura las notas. Estoy pensando como $10 al mes, o tal vez $5, o un plan gratis con límite de tareas y un plus sin límites.”
“I'll keep the service free and sell the agent… the assistant that structures your notes. Thinking $10 a month, maybe $5, or a free plan with task limits and an unlimited plus.”
The notes app's business model, first attestation: the app is free, the AI layer is the product. Same pattern as the language game's dataset store (seed 7-1): give the vessel, sell the intelligence. Pricing anchored against ChatGPT's ~80,000 COP; the saturated notes market honestly acknowledged.
Estático por ahora
“El problema era cómo hacer ese responsiveness entre el navegador y el celular… para no complicarnos mucho, lo vamos a dejar así como imágenes estáticas por ahora.”
“The problem was making it responsive between browser and phone… to keep it simple, we're leaving it as static images for now.”
The Canva-to-web pipeline produces absolute pixel coordinates, and translating those to responsive layouts broke differently on each of the five styles (grapesjs tried, animations demoed, all parked). Decision: ship static, animate one element later. The recurring pattern: simplify to ship, upgrade from revenue.
Clonar el arte previo
“Uno describe qué aplicación está buscando y esta vaina busca en GitHub repositorios públicos que ya hayan hecho algo parecido… después con el otro extraes toda la información del repositorio en un documento y ya empiezas a hacer vibe coding con esos detalles.”
“You describe the app you're looking for and this thing searches GitHub for public repos that already did something similar… then the other one extracts the whole repo into a document and you vibe-code from those details.”
A two-tool workflow spotted on LinkedIn (an AI GitHub search plus a repo-to-document extractor, names to verify): stand on prior art instead of generating from zero. Untested; licensing questions honestly flagged on camera. Logged for the next MVP.
La cédula en el cumpleaños
“Me pidieron la cédula y se cercioraron de que sí estoy de cumpleaños… entiendo que deben cerciorarse, pero es un detallito feo: feliz cumpleaños, muéstreme la cédula.”
“They asked for my ID and verified it really was my birthday… I get that they have to check, but it's an ugly little detail: happy birthday, show me your ID.”
Fraud prevention that breaks the moment it exists to celebrate. First attestation of a service-design tension worth keeping: every verification step is justified by abusers and paid for by the honest, and the best services hide the check inside the delight.
Blender por texto
“Se puede conectar Blender con un LLM… uno puede modelar o hacer cosas en Blender con texto. Se llama MCP Server de Blender: protocolos de comunicación para conectar los LLMs con diferentes plataformas, como un cerebro que hace las cosas.”
“You can connect Blender to an LLM… you can model or do things in Blender with text. It's called the Blender MCP Server: communication protocols connecting LLMs to different platforms, like a brain that does the things.”
First on-camera mention of MCP: the idea of the LLM as a brain wired into arbitrary tools. Spotted during the turbine sprint, too late to learn under deadline; flagged as the first thing to try on the next 3D project.
Los cuatro colores llegaron tarde
“Estoy acá mirando lo que está haciendo Julia, con florecitas, limones… y la cosa es que la tecnología no va para eso: son máximo tres, cuatro colores, por la investigación que yo hice.”
“I'm watching what Julia is making, little flowers, lemons… and the thing is the technology can't do that: three, four colors max, per the research I did.”
The constraint existed in his research before Julia started designing, and reached her after the lemons were drawn. First attestation of a recurring failure: constraints discovered by the researcher must be delivered to the maker before the making starts, or the difference is paid in discarded work.
La app de notas que yo usaría
“Keep se me queda chiquito y Notion ya es muy detallado, me da mamera. Entonces estoy construyendo mi sistema de notas como yo lo quiero: jerarquías infinitas, toggles, historial de modificaciones, y una IA que me las estructure.”
“Keep is too small for me and Notion is too much, it exhausts me. So I'm building my note system the way I want it: infinite hierarchies, toggles, modification history, and an AI that structures them for me.”
Scratch-your-own-itch project, first attestation: posted on Reddit, people liked it; possible subscriptions for the AI organizer. Might ship before the language game. Worth tracking which of the parallel projects reaches revenue first.
El arreglo de dos minutos
“Quedé como que ¿en serio? Llevamos quién sabe cuántos años con ese repetidor y nunca servía. Y yo no lo había arreglado porque pensaba que tenía que venir alguien.”
“I was like, seriously? We've had that repeater for who knows how many years and it never worked. And I hadn't fixed it because I thought someone had to come.”
Years of broken wifi, fixed by pressing two buttons shown in a help video. First attestation of a pattern worth hunting: problems assumed to need an expert that actually need two minutes of looking.
La IA como auxilio, no como final
“Yo pongo prompts para saber por dónde andar, hacemos como una votación de versiones, y después hago una versión mía inspirada en eso. Porque el bichito se queda con el ojo torto, no se queda con las manos bien.”
“I use prompts to find the direction, we vote between versions, and then I make my own version inspired by that. Because the little creature ends up with a crooked eye, the hands come out wrong.”
Julia's design method, first attestation: AI generates the direction candidates, the human crafts the final artifact. The opposite division of labor from vibe coding, where AI executes and the human directs. Tool of choice for vectors: Recraft.
Cuando las IAs se contradicen
“Gemini me decía que sí, que la cédula de extranjería funciona bien. ChatGPT investigaba y me decía que no, que tiene que crear un NIT con la DIAN. Al final creemos más la opción de ChatGPT.”
“Gemini told me yes, the foreign ID works fine. ChatGPT researched it and said no, you have to create a NIT with the DIAN. In the end we trust ChatGPT's answer more.”
The tiebreak protocol, first attestation: when two AIs disagree on a legal or compliance question, take the stricter answer. Being wrong cautiously costs a form; being wrong optimistically costs a sanction.
El carrusel sí, las páginas no
“Si hacemos cinco estilos por cada sección, nuestro trabajo se multiplica muchísimo. Por ahora dejamos el carrusel con los cinco estilos y las páginas internas en algo más neutro.”
“If we do five styles for every section, our work multiplies enormously. For now the carousel keeps the five styles and the inner pages stay neutral.”
Scope control caught in the act: five styles times every page times every future section is combinatorial explosion. The showcase gets the variety; everything else gets the standard. First attestation of the content-matrix trap.
La tienda de datasets
“Quiero meter una tienda con bases de datos de vocabulario que la gente pueda comprar, y por ahí es donde quiero ganar plata: para inglés B1, para chino HSK, para el examen que sea.”
“I want to add a store with vocabulary databases people can buy, and that's where I want to make money: for English B1, for Chinese HSK, for whatever exam.”
First attestation of the language game's business model: the game is free-form and AI-generated, the monetization is curated exam-specific datasets. Sell the corpus, not the game.
El software que agrega rocas
“Hay veces la gente pierde la noción de para qué es un software, y termina siendo más que una herramienta: termina retrasando más todo, creando más empecillos… más rocas en el camino.”
“Sometimes people lose track of what software is for, and it stops being a tool: it ends up slowing everything down, creating more obstacles… more rocks on the road.”
The root problem according to a lawyer with twenty years inside Colombian public institutions: systems that don't talk to each other, address forms with twenty clickable options and no keyboard. Software's only job is removing rocks; when it adds them, it has failed at the definition. A hiring thesis and a product thesis in one sentence.
Emprender dentro de una empresa
“Crear una plataforma donde uno le ayuda a las personas a emprender dentro de nuestra empresa: no tendrían que complicarse con papeleo… el emprendedor se queda con un 80% y LuarAI con el 20%.”
“Build a platform where people get to found ventures inside our company: no drowning in paperwork… the entrepreneur keeps 80% and LuarAI keeps 20%.”
Born directly from the DIAN pain: an incubator-as-umbrella where LuarAI carries the accounting, banking and compliance, and members just build and sell. Self-aware caveat included on camera: viable as long as the government stays this inefficient. The idea the video's title promised.
El sistema se puede modificar
“Al final todo es cosa de sistemas, de arquitectura… la sociedad crea un sistema, pero el sistema puede ser modificado para guiar a la sociedad a ese punto óptimo.”
“In the end everything is a matter of systems, of architecture… society creates a system, but the system can be modified to guide society toward that optimal point.”
Said about Singapore's land model, but it's the channel's thesis in one line: systems aren't weather, they're architecture, and architecture can be redesigned. The clearest on-camera attestation so far of the 'mastery is a system' pillar.
Los tiempos muertos del vibe coding
“Mientras que la vaina programa, uno no tiene nada que hacer. Uno termina entrando en TikTok, en YouTube… Lo que sí tengo que hacer es mirar cómo aprovechar mejor esos tiempos muertos.”
“While the thing codes, you have nothing to do. You end up on TikTok, on YouTube… What I do need to figure out is how to make better use of those dead times.”
The new work rhythm nobody designed for: agents introduce compulsory idle minutes, and the default filler is the scroll. First attestation of a problem that will grow as the agents get more capable.
La ventana gratis
“Como está en beta ni siquiera están contando cuántos tokens uno utiliza… siento que esta aplicación de idiomas la puedo sacar esta semana, este mes, siempre y cuando los de Google sigan dejando Jules gratis.”
“Since it's in beta they aren't even counting the tokens you use… I feel I can ship this language app this week, this month, as long as Google keeps Jules free.”
Subsidized frontier tools create shipping windows: unlimited Gemini 2.5 Pro through a free beta, today. The window will close; the MVPs built inside it stay built. Urgency as strategy.
El lector que te mira los ojos
“Una IA que le mire a uno los ojos mientras está leyendo y que maximice la velocidad de lectura… Alguna vez lo publiqué en internet y básicamente me putearon: que eso es pseudociencia. Pero mi intuición me dice que sí es posible.”
“An AI that watches your eyes while you read and maximizes your reading speed… I posted it online once and basically got flamed: 'that's pseudoscience.' But my intuition says it's possible.”
An idea from the year of studying AI: eye-tracking plus generated stimuli to keep the brain locked on the text, with comprehension checks per chapter. Publicly rejected once, privately kept. Logged so the archive remembers who said it first.
La IA persigue el objetivo que le pongas
“La IA hace lo que el humano le ponga: el objetivo con el que se ha entrenado. Si el objetivo es maximizar el tiempo que esté uno en la pantalla, lo hace.”
“AI does whatever the human sets: the objective it was trained on. If the objective is maximizing your screen time, that's what it does.”
Said while discussing TikTok's retention machine and the imagined video generator that optimizes brain-lock. The objective function is the whole game: aim it at retention and you get addiction; aim it elsewhere and you get something else. Rhymes with seed 3-2 (metrics get gamed) from the other side.
La tablita en cero
“Las empresas dijeron: vamos a poner vainas de tal manera que ya no salga nada en la tablita. Entonces uno coge una Coca-Cola Cero y dice 0%… eso es puro marketing.”
“The companies said: let's put things in such a way that nothing shows up on the label anymore. So you grab a Coke Zero and it says 0%… that's pure marketing.”
When people started reading nutrition labels, products were reengineered so the label reads zero: the metric got gamed, not the food fixed. First attestation of a Goodhart-shaped idea that applies to every dashboard we'll ever publish here.
Atacan la idea, no a ti
“Tenga en cuenta que le están atacando su idea, que no lo están atacando a usted personalmente… separar la idea de lo personal.”
“Keep in mind they're attacking your idea, not attacking you personally… separate the idea from the personal.”
Learned at the Hult Prize: a jury member rejected the rental-marketplace idea with 'I wouldn't lend my bike to anyone, it's like my son', and the team took it as a personal attack instead of a signal about audience fit. First attestation of the founder-feedback discipline.
La etiqueta del cable
“Se me ocurrió comenzar a leer el cablecito… encontré una vaina que decía 16 AWG. Le pregunté a GPT qué era eso, y era la única cosa que cambiaba entre uno y el otro.”
“It occurred to me to start reading the little cable… I found a thing that said 16 AWG. I asked GPT what that was, and it was the only thing different between the two.”
The repair shop was lost; the laptop showed a low-power error nobody could explain. Reading the cable's printed spec plus one GPT question found what the technician couldn't: the replacement cable was 18 AWG, thinner than the original 16. First attestation of a theme: AI collapses everyday expertise gaps for whoever bothers to look closely.
El miedo que congeló la app
“Si una de las personas de la plataforma rompe algo en una casa, se roba algo… ¿qué hacemos? De ese lado como que nos asustó un poco. Igual esa idea no la hemos descartado.”
“If one of the people on the platform breaks something in a house, steals something… what do we do? That side scared us a bit. Still, we haven't discarded the idea.”
The toderos-clients app had its logic fully built. It stopped on legal-liability fear and missing capital, not on technology. Parked, not discarded. First appearance of a theme worth watching: what actually kills projects.
El capitán y la receta
“La IA puede hacer recetas que ya existen, pero no me puede hacer una receta completamente nueva y única… que sea como la herramienta que nos ayude a realizar lo que tenemos en la cabeza, y no que sea la cabeza de nosotros.”
“AI can cook recipes that already exist, but it can't make me a completely new and unique one… let it be the tool that helps us build what's in our heads, not become the head itself.”
First recorded statement of the human-as-captain thesis: AI as executor, the human as the source of direction and taste. Stated lightly here, in passing; expected to mature into a full argument in later videos.
