No - I read that a few years ago, and couldn't really get Penrose's point. He seemed to be postulating some sort of mystical component to thought because he couldn't face, philosophically, the idea that human brains might be just another Turing machine. The book I just read is Ray Kurzweil's "The Age of Spiritual Machines": an alternately exhilarating and disturbing look at the future of artificial intelligence. He makes a pretty impregnable case for the idea that we as human beings will be replaced, either by enhanced humans or AIs, sometime in the next 25-20 years...
