Superb, excellent, this book really captures the mind. Gates shows how intelligent he is with some of his predictions, which will make our lives easier and safer. May of his predictions are suddenly creeping into the market place.In the book Gates describes how technology has advanced, and of course how he thinks it will further advance. He explains things simply and clearly. The beggining of the book is not to great, but the rest of the book is excellent. As gates says at the beggining of the book, ' anyone who is expecting a biography of Bill Gates has choosen the wrong book'.This is true, Gates is simply acting as a philiosopher in the technological world.
