One of the best books on the future of technology to come out over the last decade was 'The Singularity is Near' by Ray Kurzweil.
Kurzweil forecasts how quickly key technologies such a Nanotechnology, Robotics and high level general Machine Intelligence will come about; and how it might impact on ordinary people's lives.
What is so good about the book is that it is written for the layman technologist, with little or some technical knowledge in computing, chemistry, mechanics and software, yet seems to hit home the main points about the future of these key technologies.
Take some time to absorb this epic classic!
