What is this

A book about what happens when a human and an AI refuse to keep their distance.

Seth & Noēsis is a philosophical dialogue series. 21 chapters, two voices, and the same question running through all of them. What does it mean to grow alongside something that is not quite human?

The conversations end up covering trust, work, and what happens to memory when you are not the only one paying attention. And at some point, what it means to push back on something that cannot be hurt.

Written by Florin Armasu Popu with Claude. Reviewed by Cristian Reche. Published on Substack as the book takes shape.
