Emphasizing the importance for societies to build in self-correcting mechanisms (like the Constitution that can be amended not holy books that claim to be infallible) and recognizing the importance of addressing the “alignment problem” artificial intelligence presents, Harari offers a realistic, not apoplectic ,perspective on the future. The future, he reminds us, is not pre-determined. The decisions we make moving forward will decide our fate. This book is a window into one type of world, or another, we can create, depending on those decisions.
