Cover of Co-Existence: The Next Phase of AI by Ethan Mollick — two hands reaching toward each other from Michelangelo's Creation of Adam against a bright cloud-filled sky.

About the book

The question used to be whether to use AI. Now it’s how to live alongside it.

When Ethan Mollick wrote Co‑Intelligence, working with AI meant prompting a chatbot that couldn’t do basic math. A short time later AIs are winning gold at the International Math Olympiad, reshaping professions from programming to medicine, and helping authors make really nice looking web sites for their new books.

Co‑Existence is a field guide to this moment, written in, and about, a time before true AGI. With the warmth, humor, and deep research that made his last book a bestseller, Mollick draws on the latest data and real‑world cases to answer the questions everyone is actually asking:

  • How do I work alongside something that may be smarter than me (sometimes)?
  • What does this mean for my job, my company, my kids’ school, and human society?
  • What can AI really do today… and how do I tell genuine capability from hype?
  • How do I stay in charge of my own thinking when a machine can finish my sentences?
