I must confess I did not end up reading the whole thing cover to cover. I started at the back with his conclusion, recognized his complete naivete of the real world, and excessive optimism due to (I assume) having been a gifted scientist and achieving high status without having ever had to be on food stamps or be a retail clerk. He was a co-founder of string theory, so that kind of says a lot by the fact that most people have heard of it, even if only because Sheldon Cooper of The Big Bang Theory used to research this aspect of theoretical physics.
