This is something of a ragbag ranging far and wide over neuroscience, consciousness, intelligence, mental illness, mind control, dreams, NDE, robotics/artificial intelligence, aliens and a good deal of futurology. Any one of these topics might have justified a book from this author, but what we get here is mainly a series of superficial commentaries.
As far as any persistent themes can be detected, these seem to revolve round consciousness and the development of robotics/artificial intelligence. The theory of consciousness suggested here is really only half a theory, giving consciousness the function of providing models of the future, without explaining either why such models require consciousness, or how consciousness might arise in the first place.
The exploration of robotics and artificial intelligence is similarly unsatisfactory. The lack of any progress to date in producing properly autonomous robots is detailed. It is noted how the much-hyped Watson computer appears to lack any capacity for appreciating its own sucess, or socialising with the humans around it. Nevertheless, after describing all this, the author still follows the party line of projecting forward to the triumph of AI/robotics without much suggestion of why the future will be more successful than the past.
Perhaps these shortcomings are at least partly redeemed by an insight at the very beginning of the book, where it is suggested that the introduction of brain scanning since the 1990s is as significant as the invention of the telescope for the scientific understanding of our world.
