This book was pretty fascinating, if only for the discussion of humanity's technological future. While I've only recently begun watching the new series of Doctor Who, aliens and conspiracy theories have always been fascinating. While Parsons tends to wax quantum-theoretical (a bit trying for my mere high school physics education), the language is understandable enough and the concepts fairly easy to grasp (if trying to grasp the concept of the Universe and what may have existed before or what may exist after it's end is fairly easy). Overall good read. And I will definitely be looking up cybernetic implants.
