Co-Existence: The Next Phase of AI
Ethan Mollick · 2026 · Portfolio
A Wharton professor's guide to living and working with AI systems that are sometimes, but not always, better than you. Published October 20, 2026, as the follow-up to Co-Intelligence.
Summary
This book examines how to live and work alongside AI systems whose capabilities vary from task to task. The author describes AI capability as a jagged frontier rather than a smooth line: tasks that look simple can fall outside it while complex ones fall within it, and users often cannot predict the boundary in advance. The book argues for testing where AI helps, verifying its output, and keeping human judgment central rather than trusting or dismissing the technology wholesale. It draws on a research base of close to 200 references, including a field experiment with 758 Boston Consulting Group consultants that found AI improved performance on tasks inside its capability frontier and reduced it on tasks outside it. Topics span work, education, learning, agents, and the future of human-AI collaboration.
