Rees certainly highlights the risks currently facing humankind as well as those we will likely face in the near future. But I find most of his predictions, although certainly not impossible, bordering on science fiction and, thus, merely speculative. Moreover, I find it difficult to accept that science and technology will provide solutions, given that they are, in many ways, largely responsible for many of the dangers we now face. The wonders of IT advances, although very useful to those who use it for legitimate research and study designed to benefit the human race, have also resulted in the creation of a generation of smart phone and social media zombies who are mostly oblivious to what goes on around them, as well as, the ability of governments to spy on the most private aspects of our personal lives. As long as, private corporations control scientific and technological research and development, the abuses inherent in unfettered capitalism give me every reason to doubt that future advances in these fields will be blessings.
