The rapid forward march of technology has long bred two leading camps of onlookers: the techno-optimists and the techno-pessimists. Honest people on both sides, however, must admit that technological innovation has had both positive and negative effects. Internet legend Tim O'Reilly is one of the people who think a lot about these issues, and his new book WTF? What's the Future and Why It's Up to Us — which discusses in detail the world that we are building with technology — was released today, and we're pleased to have him join us on this week's episode to talk about the book and the future of innovation.
