Every technology has parents
The book is drawn as a tree, because that is how technology grows: each invention springs from the ones before it. Read it from the roots up, the way history happened, or jump to any branch that interests you.
The rootsThe Prologue: December 1947, a sliver of germanium makes a voice louder. Everything grows from here.
The trunkThe thread that runs through the whole book: machines that calculate, then obey, then connect, learn and act.
