We stand at the beginning of a new era. What was once science fiction is quickly becoming reality as AI transforms war, crime, justice, jobs, and society – and even our own understanding of what it means to be human. More than any other technology, AI has the potential to revolutionize our shared future, and no one is better suited to explore this future than Max Tegmark, an MIT professor and co-founder of the Future of Life Institute, whose work has helped establish research on how to keep AI beneficial. In this thoroughly researched and critically important new book, Tegmark takes us to the heart of the thinking about AI and human existence, confronting us with the fundamental questions of our time. What kind of future do we want? Life 3.0 gives us the tools to engage in what may be the most important conversation of our time.
