Large-scale human cooperation runs on things that don’t exist. Money, nations, corporations, and gods are invented realities, and they work only as long as enough people believe in them. That is the engine behind everything Homo sapiens has built, and the reason we came to dominate the planet. When Homo sapiens appeared about 300,000 years ago in East Africa, we were no more remarkable than any other animal. What changed everything was the Cognitive Revolution: language sophisticated enough to share not just information but ideas about things that aren’t physically real. With shared fictions, humans could cooperate flexibly in enormous groups, far beyond the handful of people who can actually know one another, and that let us unify and conquer.

The people who own the data and biotech of this century may end up owning everything, including us. That threat runs under all twenty-one of Harari’s essays. Whoever masters the ability to predict and shape human behavior at scale could fracture our species into a genetically and cognitively enhanced elite and a vast underclass with no economic use at all. The old stories that once organized political life—fascism, communism, liberal democracy—all spread through simple emotional narratives rather than data, and any story that wants to matter now has to make sense of artificial intelligence, big data, and bioengineering. That is hard, because humans have always been better at building tools than foreseeing what they do. It is easy to dam a river; it is nearly impossible to predict what the dam does to the whole ecosystem. The same goes for redirecting the flow of our own minds.
