Mark Stevenson has been to the future a few years ahead of the rest of us – and reckons it has a lot going for it. His voyage of discovery takes him to Oxford to meet Transhumanists (they intend to live forever) and to Boston where he confronts a robot with mood swings. He clambers around space planes in the Mojave desert, gets to grips with the potential of nanotechnology, has his genome profiled, and glimpses the next stage of human evolution. Perhaps the future is not all doom and gloom?
