Published Known Unknown — a free book on life after AI

Published Known Unknown, a free 14-chapter book exploring what happens to human existence when AI transforms everything. The book moves from present-day AI through agents, economic disruption, augmented environments, neural links, and biological augmentation. It is written for non-specialists, available as a free PDF, and does not claim to predict the exact sequence of events — it treats the future as structurally unknowable and still worth reasoning about.
