The future of humanity is bound to the future of science, and our prospects hinge on how successfully we harness technological advances to address the challenges to our collective future. If we are to use science to solve our problems while avoiding its dystopian risks, we must think rationally, globally, collectively, and optimistically about the long-term future. Advances in biotechnology, cybertechnology, robotics, and artificial intelligence--if pursued and applied wisely--could empower us to boost the developing and developed world and overcome the threats humanity faces on Earth, from climate change to nuclear war. At the same time, further advances in space science will allow humans to explore the solar system and beyond with robots and AI. But there is no "Plan B" for Earth--no viable alternative within reach if we do not care for our home planet.
"Fortunately for Rees, the symptoms of his anxiety appear to be an exceptionally clear head and a capable grasp of the big picture. His sense of cosmic wonder shines through brilliantly in the book's later chapters. Explanations of complex subjects like the Large Hadron Collider and the ongoing search for exoplanets benefit from his crisp, precise prose. . . . Rees is a seasoned science communicator, and in so far as his job is to get more and more people interested in the field, the book's short length and approachable style is a shrewd move that will open a wormhole to the big questions for the curious."---Louie Conway, Vanity Fair
