Ray Kurzweil's Dubious New Theory of Mind

Ray Kurzweil is, by all accounts, a genius. He holds nineteen honorary doctorates, has founded a half-dozen successful companies, and was a major contributor to the field of artificial intelligence. He built some of the first practical systems for recognizing speech and scanning text. Time magazine recently featured Kurzweil on its cover, and Fortune described him as "a legendary inventor with a history of mind-blowing ideas." And now he has a new book, with a subtitle that suggests he has found another such idea: "How to Create a Mind: The Secret of Human Thought Revealed."
