Ethan Mollick - Co-Existence: The Next Phase of AI | Paperback

This essential follow-up to the bestselling Co-Intelligence provides a critical guide for navigating the complex and uneven landscape where human and Artificial Intelligence capabilities intersect. Written by Wharton professor Ethan Mollick, this book addresses the reality that AI is already deeply embedded in modern life, capable of reasoning, planning, and creation in ways previously unimaginable.

The core concept explored is the 'jagged frontier'—the unevenness of AI capability where systems excel dramatically in some areas (peaks) while failing at simple tasks (valleys). This instability defines the future of work, requiring humans to master navigating these volatile overlaps between machine strengths and human intuition.

• Analyzes the 'jagged frontier' where AI excels beyond human ability and where it fails completely.
• Provides a clear, practical framework for thriving where human and machine intelligence meet.
• Argues that human navigation skills remain essential for handling the uneven capability of current AI systems.
• Written by Ethan Mollick, author of the widely read One Useful Thing newsletter.
