I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Surprise! The last three chapters are about robots and swarm intelligence's applications in artificial intelligence.
According to my records, in the past 10 years I've only read or listened to approximately 13 nonfiction books, so finishing this counts as an accomplishment. The last nonfiction book I finished was in October 2017.
My final rating will probably be 3 or 3.5 stars. Probably 3. This was very readable, but its organization wasn't great, and some of the info opened up huge questions that the authors didn't acknowledge in any way.
