Query: Should be 0 stars; but this machine doesn't allow that.

There is very little science in this book. It is really about Kurzweil's ego. He frequently implies his software is the future of computing. His "most significant event" for 1999 is the publication of this book. Such self serving hype is unforgivable.Predictions for 2009 are easily extrapolated from today's technology (probably because he will be around to be held accountable). Longer range predictions are pure SCIENCE FICTION. According to Kurzweil, humans will become borg-like drones, or even worse, extinct; replaced by self replicating machines. No way!There are some interesting bits of computing history, but even these facts are distorted to promote Kurzweil's agenda.Save your money. Pulp science fiction has more integrity than this book.
