In content it is something anyone could have written, knowing a bit about present science affairs and doing a bit of research. But who better than a well-respected scientist! It collates information from brains around all corners of the world, which founds some validity in the predictions. The book is written simply (i.e. for an educated layman) and even the sometimes laborious facts, somehow seem to encourage enthusiasm towards the next century. One to keep until 2020 (at least) to see whether these crystal-ball visions really do come true!
