This book got me excited. It changed the way I think about the future, and I recommend it to anyone who wants to understand the possibilities that the future holds.
Kurzweil presents his theories a lot more convincingly than I can, but I've certainly tried a lot since I read this book. It stimulates philosophical debate on the nature of life and intelligence, but grounds its philosophical wanderings in believable theory.
The book is not without its problems. The jump into the future of nanotechnology leaves is abrupt and the Law of Accelerating returns is not a law but a trend. He ignores the possibility of social movements or government action to prevent Artificial Intelligence research once it reaches a certain level. When he speaks about specific aspects of humanity or sex, he reveals an incomplete understanding of the way people feel and love.
But these flaws only serve to remind the reader that the book is indeed speculation, not fact. And the speculation is beautiful, absolutely inspiring. It introduced possibilities and ideas that I'm still turning over in my mind, and it did it all with clear, entertaining writing that a non-scientist like me can understand.
Pick up this book, read it, make your friends read it, and enjoy the time you spend discussing it. The resulting conversations will be so much more interesting than your usual social fare.
In fact, read a book like this every year, whether it's something totally off the wall (Robert Anton Wilson's "Prometheus Rising") or a little more grounded in current science (Kevin Kelly's "Out of Control"). It will broaden your "reality-tunnel" and get your mind working with big, fun concepts.

Format: Hardcover
Ray Kurzweil's "The Age of Spiritual Machines' is an intelligent look at what the future might be holding for us all. Like other similar titles - Visions by Michio Kaku comes to mind - Kurzweil tries to predict where science will take us. Unlike `Visions' however, this book is considerably more focused on computer technology and artificial intelligence, and I would only recommend it if you're not looking for a much broader answer to the question of where we are headed. Kurzweil never intended to cover other matters, and reading the Prologue will be enough to understand that most of the book will explore the rising of machine intelligence to a level that will surpass the capabilities of the human brain.
Kurzweil starts by describing the exponential growth of computer power, Moore's Law, and transistor-based computing. The present and the future are described until quantum effects start becoming a problem and a completely new kind of technology becomes necessary (some alternatives are mentioned, Quantum computation is of course, mentioned). The book proceeds to more metaphysical subjects, and questions if we can create another intelligence form more intelligent than ourselves. Can the created exceed the creator?
It will then proceed to cover consciousness and feelings; Kurzweil gets philosophical in what in my opinion is one of the book's weakest chapters The methods available to solve a wide range of intelligent problems (when combined with heavy doses of computation) will follow, in a chapter that covers subjects from recursive formulas to neural nets, and of course, enough space is dedicated to Alan Turing, the father of all modern computers.

Ray Kurzweil is well known for the myriad of inventions he has pioneered, from the original Kurzweil Synthesizer through a series of computerized appliances designed to make life easier for the handicapped. He is less well known for his previous book, "The Age of Intelligent Machines," and for his shockingly accurate past prognosticating on the future of technology (he missed calling the chess match victory of Deep Blue against Kasparov by one year...making the prediction a decade or more ago). Now Kurzweil is weighing in on what the astounding exponential advance of computer processing power is going to mean to the human race. In short, he goes way, *way* out on a limb, and flatly predicts that human minds and bodies will have largely combined and integrated with super-powerful computers within 100 years from today. Furthermore, he convincingly extrapolates present advances in computing power to predict that a $1,000 desktop PC in the year 2020 will have equal computing power to a human mind. Then 40 years after that, by 2060, a desktop computer will have the combined computing power of every human mind on earth. And that curve will continue increasing until individual computers within the next hundred years will have the computing power of billions of human minds. In the face of that, Kurzweil predicts, human beings will assimilate with the new super-intelligence of machines, in order to bypass biological evolution and supercharge not only our minds but also our bodies, which will be remade and redesigned in virtually any way we might find compelling and useful. In short, Kurzweil is predicting the emergence of a new species within the next 100 years, as machine intelligence exceeds carbon-based intelligence by millions of powers. Scary? Not at all.Read more ›
