The Nervous System
How AI Learned to Feel Its Way Through the World — and What Happens When It Starts to Trust Itself

These are not gadgets. They are dendrites. And they are growing.
The dominant story about artificial intelligence — the one that fills senate hearings and science fiction plots and the manifestos of people who should know better — is a story about a brain. About the moment when a machine becomes, in some meaningful sense, a thinking thing: self-aware, recursive, motivated. The story has a villain (the superintelligence), a threshold (the singularity), and a protagonist (humanity, racing to maintain control before that threshold is crossed). It is a tidy story. It is also almost entirely wrong, not in its details but in its anatomy. We have been so focused on whether AI would develop a mind that we failed to notice it was building something older, stranger, and more immediately consequential: a body.
Or more precisely: a nervous system. The distinction matters enormously, and the rest of this book depends on it,
