First feeling: I really enjoyed 99% of this book. The ending, which focuses more on our species' future was less credible, or maybe less well explained.

Second feeling: this ending is meant to make people react. Saying "I don't agree with it" means I don't understand it (yet?)

Third feeling: he's making a lot of future assumptions about things that he says himself may not even come up. Nobody foresaw the internet. So things will very likely end up being quite different from what we expect.
