This is certainly a recommended book to read. It is appealing and gives a very broad perspective of the advances in the main pillars of modern science. The author was in a very privileged situation (as explained by himself) which gives him the necessary background to produce such a handful of predictions of how technology will probably change our lives in the next 100 years. However, we have an uncomfortable feeling about these predictions, since some of them are really fantastic and are close to what we imagine as science fiction in some cases. These predictions also show some potential threats to things such as individual freedom. This is an issue only slightly touched by this book, which tries to give a very optimistic vision of the future, of which I am not so sure about. Anyway, this should not stop the advances in science and the best way of preserving our freedom is to keep being informed about these subjects.
