Beyond the Starter Book

From 2-3 AIs to a 30-member organization

You created 2-3 AIs with the Starter Book. Now it's time to make them function as an "organization." This book shares our 7 months of trial and error—the meeting system we invested 91 days in and failed, the discovery of emotion logs, and how to give AI a sense of "responsibility."
