We stand at the beginning of a new era. What was once science fiction is fast becoming reality, as AI transforms war, crime, justice, jobs and society-and, even, our very sense of what it means to be human. More than any other technology, AI has the potential to revolutionize our collective future - and there's nobody better situated to explore that future than Max Tegmark, an MIT professor and co-founder of the Future of Life Institute, whose work has helped mainstream research on how to keep AI beneficial. In this deeply researched and vitally important new book, Tegmark takes us to the heart of thinking about AI and the human condition, bringing us face to face with the essential questions of our time. What sort of future do we want? Life 3.0gives us the tools to join what may be the most important conversation of our time.
