“This book is a brilliant chronicle of encounters with our future selves, even as we already experience the vertigo of changing. Drawn from real conversations with living visionaries, Duncan takes us to the crossroads of the inevitable merging of human and machine. Splendidly written, passionately argued, and well-researched, this book is a divination tool for the arrival of either the utopia or the apocalypse.”--Andrei Codrescu, author of Raised by Puppets Only to Be Killed by Research: essays from NPR
