Harari is strongest when he analyzes the long sweep of human history as he did in Sapiens. His analysis of how Humanism evolved during the Enlightenment as a quasi-religion is insightful and serves as a useful framework for thinking about the role of religion in modern society.
As he speculates on the future of mankind, he offers some thought-provoking ideas. His scenarios of increasing inequality as the rich take advantage of biotech advances are probable, but he ends off veering into improbable Kurzweil-like scenarios of humans being supplanted by big data and AI. Uneven, but still recommended.
