Take what you read here with a grain of salt. Harari is a historian, not a scientist or engineer. When his writings touch these topics, which is most of the time, it is implausible speculation, based on sensationalist guesswork by popular science journalists. Go through the chapter on Work, for example, and count how many sentences start with "What if." First, does anyone who knows what they're talking about think these what-ifs might come to pass, and second, I'm looking to you, Harari, to tell me what's going to happen, not ask me!
Worth looking into, but not as good as the previous two books, which were works of history. One might suspect it was written to capitalize on their success. Comes across as a sophomore bull session, or what we used to call mental masturbation, meaning that it feels good to think about, but it just doesn't get the job done, if you know what I mean, and I think you do.
