Author Michael Chorost visits Google's headquarters in Mountain View, CA, to discuss his book "Rebuilt: How Becoming Part Computer Made Me More Human". This is the story of Chorost's journey -- from deafness to hearing, from human to cyborg -- and how it transformed him. The melding of silicon and flesh has long been the stuff of science fiction. But as Chorost reveals in this witty, poignant, and illuminating memoir, fantasy is now giving way to reality.
