In his first book, 'Sapiens: A Brief History of Humankind,' which became a worldwide sensation, Yuval Harari described how Homo sapiens came to dominate our planet. 'Homo Deus' is a continuation of this theme—an attempt to peer into the future. What will happen when Google and Facebook know our tastes, personal sympathies, and political preferences better than we do ourselves? What will billions of people do, displaced by computers from the labor market and forming a new, useless class? How will religions perceive genetic engineering? What will be the consequences of the transfer of authority and competence from living people to network algorithms? What must humans do to protect the planet from their own destructive power? The main thing now, Harari believes, is to recognize that we are at a crossroads and understand where the paths stretching out before us lead. We cannot stop the course of history, but we can choose the direction.
