...or at least that's what Ray Kurzweil thinks. He has spent his life inventing machines that help people, from the blind to dyslexics. Now, he believes we're on the brink of a new age - the 'singularity' - when mind-boggling technology will allow us to email each other toast, run as fast as Usain Bolt (for 15 minutes) - and even live forever. Is there sense to his science - or is the man who reasons that one day he'll bring his dad back from the grave just a mad professor peddling a nightmare vision of the future?
