Yuval Noah Harari on the power of data, artificial intelligence and the future of the human race

When Yuval Noah Harari published his first book, "Sapiens," in 2014 about the history of the human species, it became a global bestseller, and turned the little-known, Israeli history professor into one of the most popular writers and thinkers on the planet. But when we met with Harari in Tel Aviv this summer, it wasn't our species' past that concerned him, it was our future. Harari believes we may be on the brink of creating not just a new, enhanced species of human, but an entirely new kind of being - one that is far more intelligent than we are. It sounds like science fiction, but Yuval Noah Harari says it's actually much more dangerous than that. Anderson Cooper: You said, "We are one of the last generations of Homo sapiens. Within a century or two, Earth will be dominated by entities that are more different from us than we are different from chimpanzees."
