Ethan Mollick on Coexisting with AI, at Scale

Mollick argues AI gains require organizational restructuring, not just adoption, and the human-in-the-loop model is already obsolete for delegated tasks.

• Co-intelligence era ending: Mollick's new book Coexistence (Oct 20) argues the human-in-the-loop model is closing as users delegate entire tasks to AI agents they no longer take back.
• No firm-level gains without reorg: BCG study of 700+ consultants showed GPT-4 users completed 12% more tasks, 25% faster, 40% higher quality — but 19pp worse outside AI's capability zone; coders write ~17x more code with no appreciable error increase, yet firms won't see large gains until organizational structures change.

Themes, sentiment and reasons are AI-written paraphrases, checked so they never quote an episode. They may contain errors. Not investment advice. Episodes remain the property of their creators.
