Alexandre Langkay Peschel

I build things and I write about what it reveals to me.

Right now that means agent teams, and the question underneath is not a technical one. Can working with a machine make a person more capable, or only faster at what they could already do?

Before that I spent four years on climate tech and left when the bottleneck turned out to be somewhere else.
