Co-Existence

How do we live alongside machines that are sometimes smarter than us?

We are entering a new era. AI systems can already outperform humans in some domains while failing spectacularly in others. They can act as tutors, collaborators, researchers, strategists and creators … yet they can also produce falsehoods, generate convincing nonsense and fail unpredictably. The challenge is no longer simply adopting new technology. It is learning how to think, work and live in a world where machines are sometimes smarter than us.

In Co-Existence, Ethan Mollick – a Wharton professor and author of the widely read One Useful Thing newsletter – argues that the future of AI will not be defined by replacement, but by interaction.

Drawing on years of research, experimentation and frontline experience with rapidly evolving AI systems, Mollick shows readers how to:
work productively with AI while retaining judgment and autonomy;distinguish where human insight matters most;avoid becoming overly dependent on systems designed to persuade and imitate;adapt creatively as AI reshapes education, business and everyday life; andbuild a durable human advantage in a world of intelligent machines.
Clear-eyed, practical and written with warmth and humor, Co-Existence is your guide to navigating the next phase of the AI revolution.

‘Ethan Mollick – who understands how to use AI better than anyone else on the planet – explains how it really works and why AI is qualitatively different from any technological advance before it.’ ANGELA DUCKWORTH

‘Co-Existence is an indispensable guide to navigating the jagged frontier where technology and humanity meet – and to harnessing the extraordinary possibilities that emerge when they work together.’ DOUG McMILLON
