Earth rising over the grey lunar horizon, seen from Apollo 8

Federico Carrone

I build and write at the intersection of technology and culture. More than a decade ago I founded LambdaClass, where we make Ethrex, Concrete, and Lambdaworks, and with our partners we built pamm.wtf: billions of dollars flow through these systems every month. Over the last two decades, with the teams I’ve worked with, I’ve helped build systems used by millions of people across different industries. On the culture side I’m building 421, a magazine about culture and technology. I direct the academic committee of the Centro de Criptografía y Sistemas Distribuidos at the University of Buenos Aires, and through Ergodic Group I hold companies across distributed systems, AI, gaming, wine, and culture. Here I write about things that take a long time to play out.

Written with an LLM, mostly Claude. The ideas and the mistakes are mine. How that works
