Well, we just rotated every single key across a large number of projects very quickly, and I'm struck by the fact that this would have been an absolute nightmare not too long ago
The defensive aspect of AI for cybersecurity is really underrated
Where the nuclear weapon analogy breaks down with AI is that you can't stop a nuclear weapon with another nuclear weapon
But you can stop an AI attack with an AI

One thing the engineering community will (re)discover is that every program can be ① hardened (edge cases squashed, inputs tightened, errors handled) and ② optimized (profiled, benchmarked, rewritten) basically ad infinitum.
There are real costs in every direction: time, attention, opportunity. You can literally explore input spaces that will never be hit or optimize performance of something that will never be used ("you have no users".) Even in an infinite token world, you need to know when to stop and what tradeoffs to accept. Agents will happily drill no matter what.

My take… everyone outside of tech has dealt with subpar software and shitty “chatbots” for so long that they are engrained to think these things suck. They aren’t wrong either.
Over here in tech, we are spending basically every waking moment optimizing these “agents” and they still suck a lot of the time.
If the normies are going to adopt these things in their every day life, they have a long way to go.
Hot take… isn’t it kinda crazy that nobody is really using AI Agents? I don’t mean software engineers or AI early adopters. I mean “college friends talking about it in group chat,” the feeling you got when everyone started using Instagram or TikTok.
These frontier AI models are *insane* (as are the harnesses & tool calls & the like). And every large tech co has an AI agents platform, not to mention all the YC startups doing vertical agents. Yet all of your friends and family outside of tech — who spend all day staring at their iPhones and get paid to work in browser tabs — don’t really care or find themselves using any AI agents yet.
Yes ChatGPT, Claude, etc. are extremely popular… but if you look at the engagement data the vast majority of people are still using these aI chat tools like a glorified Google + Grammarly. That’s why the AGI labs are all pushing desktop apps for Codex, Cowork, etc. so hard to non-technical ppl. And yes exceptions for lawyers and customer service but even those have some asterisks and exceptions to rule.
Look I’m not saying the ChatGPT moment for AI Agents is not coming… it most definitely is! Remember we pivoted from Arc to Dia precisely because we believe computing is going to be radically reimagined around these AI primitives. No doubt. But that’s my point: it’s just so surprising it hasn’t happened yet because all of the tech you’d need is there.
Again if you stop for a second and think about it… for all the press and money and hype and models and crazy ARR numbers… this “AI Agent” moment does not *feel* like the other breakthrough tech moments we’ve lived through (e.g. think the shift to Stories via Snapchat & Instagram, or shift to on-demand via Uber/Airbnb/Doordash).
Which is a long way of saying: if you can figure out the answer to “why” most people don’t care about AI agents yet (and have no enduring interest in using them) — especially since the models and harnesses are here and ready — the answer to that question will allow you to capture a lot of marketshare and make a lot of money in 2027.
Theoretically, the tech is ready for AI Agents to totally transform how we work and live our lives… but alas the general public dgaf… that’s the generational puzzle to solve for the next 12 months for anyone not working on the models themselves.

I’ve spent well over 10,000 hours studying math in my life, yet I can’t understand these proofs, at least not without weeks of digging deep into each topic. What’s more, none of my math PhD friends know much about these problems either, and they can’t verify most of them without working directly in the field (yes, math is VERY diverse).
LLMs are getting smarter than the experts themselves, and I’m not sure we have enough bright human minds to verify everything that will come out of them in the coming years.
Remember when we compared AI intelligence to PhD students? I think we’re past that.
An internal version of Astra, @OpenAI’s next major model family, solved 10 major open problems in mathematics, quantum complexity, and theoretical computer science.
We believe it will be a major step for scientific reasoning. openai.com/index/ten-advance…

la verdad que dude si compartir esto
pero es de las cosas que me recuerdan que todo el esfuerzo vale la pena, y que no importa cuantas veces tropiece, hay que volver a levantarse
meterle pasión paga con creces y no existe más grande recompensa que esta

Rebill fue seleccionada para el programa ScaleUp de Endeavor.
Endeavor eligió cinco compañías que están empujando sus industrias desde Argentina hacia afuera, y Rebill quedó entre ellas, junto a Bioeutectics, El Dorado, Galo AI y Maslow. Entrar a una red que ya acompañó a cientos de emprendedores en 16 países es un reconocimiento que valoramos mucho.
Construimos infraestructura de pagos que le permite a una empresa cobrar en todo el continente americano sin abrir una sociedad en cada país. En el último año nuestros ingresos crecieron 905%.
Detrás de ese número hay años de trabajo, socios con los que empujo todos los días, y clientes que confiaron en nosotros. El reconocimiento es tan de ellos como nuestro.
Gracias a Endeavor Argentina por la confianza. Y gracias a mis socios, Nahuel Candia, Ruben Maier Enzler y Francisco Andrés León, y a cada persona del equipo de Rebill, por construir esto juntos.
Vamos por lo que viene.

the most annoying things of the world cup are the people with no clue about futbol, its rules and how difficult world cups are. they never watch a match but are experts at it

For 50 years, software engineering ran on code rationing. Writing code was expensive, so we rationed it carefully through roadmaps, RFCs, prioritization meetings, and scope reviews.
This created a role: the No Engineer. No, that won't scale. No, we don't have bandwidth. No, that's out of scope. No, we need a design doc first. The No Engineer was valuable for 50 years. Every "no" saved real money. Their judgment was the rationing system.
LLMs will be the end of code rationing. Code is cheap now. And while the No Engineer is explaining why something can't be done, the Yes Engineer has already shipped three versions of it.
If you're a Yes Engineer, the next decade is yours.

estoy hace años escondiendo está parte de mí
y me cansé de hacerlo
ví lo que pasó con @JuanCereigido y @arielsbdar en Endeavor: es un dolor grande cuando queres contar tu crecimiento y emprendimiento al mundo y solo recibis odio.
quiero que conozcan esta parte de mí, mis sueños, objetivos, miedos, fracasos y aventuras
este año va a ser uno de los más complejos de mi vida (como todos jajaja) y quiero documentarlo
building in public begins
como dicen en @500GlobalVC realise before ready, pals!
episodio 1: emprender, fracasar, repetir.
shoutout to @marclou for being such an inspo!
si sos nerd, seguinos @nerdconf_ar 🤓
