Authors Marvin Cetron and Owen Davies examine anticipated trends in technology over the next 15 to 20 years. They categorize their studies under digital systems, the Internet, high-tech materials, nanotechnology, transportation, space, energy, medicine and environmental remediation. They examine specific technological proposals and estimate their chances for success within the next two decades. An appendix lists specific predictions and the probability that each will come to pass. The book is necessarily superficial, since it covers such a broad range of topics. Unavoidably, some predictions are already somewhat dated, particularly those about industries that undergo constant, rapid change, such as medicine, computers and the Internet. However, the book provides a thorough survey of the range of technologies that are under study and development. This book is a rich source of ideas and makes interesting connections among disparate technologies. We [...] recommend the book to all corporate planners, trend-researchers and long-term thinkers.
