Dedication

One day, son, you will get the keys to a kind of magic I did not have growing up — a machine you can simply talk to, that can teach you anything, help you make almost anything, and do the work of a whole team. It will shape your life more than any tool of mine shaped mine.

This book is what I would sit you down and tell you about it — the wonder, the way in, and the warnings. I wrote it so it would make sense to you at ten, and to anyone, anywhere, starting from zero.
