Ethan Mollick Announces Co-Existence, a Sequel Book on Working Alongside AI

Ethan Mollick is releasing Co-Existence on October 20, a new book about working with AI systems that are sometimes, but not always, better than humans.

The book follows his 2024 title Co-Intelligence, which he says was written about an era of chatbots rather than autonomous agents.

Mollick also reports writing every chapter draft himself while using AI readers and fact-checkers, and building the book's website with Claude Code using Opus 4.8.
