Every single page in this fascinating book is packed with breath-taking revelations about future technology, all firmly grounded in what is being done today, and where it is going. As a fiction writer who reads science books to harvest facts in which to bed my stories, I found this to be one of the most helpful books ever. Its strength is the sheer breadth of material gathered from many scientists. To his credit, the author doesn't opt for the lazy editor's method of simply copying and pasting chunks from other people's research, rather he explains it in his own words, clearly, concisely and most importantly, in ways that a lay-person can understand, a rare skill among scientists. Some of his suppositions about the future are obviously open to challenge, and I think he probably under-estimates people's reluctance to change and to adopt new technology. For example, I think his suggestion that people will wear contact lenses to access the internet, and that computers as we know them will become redundant may certainly apply to a few people in developed countries, but not to the population at large for a very long time, if at all. Not many of us will wear clothes smart enough to call an ambulance when we have accidents, or have replicators in our homes which can manufacture household items from raw materials. But I could be wrong, and he might be right. Despite those reservations, this remains in my top five of all-time science books, and I cannot recommend it too highly.
