Eliezer Yudkowsky and Nate Soares wrote a book about superintelligence, called If Anyone Builds It, Everyone Dies. It was released last week. The book is now a New York Times bestseller. It is endorsed by leading scientists across many fields, including a "godfather of AI" and the most cited living scientist; by national security experts and former government officials; by journalists; by many other public figures. Max Tegmark, the MIT physics professor, calls it the most important book of the decade. Stephen Fry says it's the most important book he's read for years. No surprise. In the coming years, humanity could develop a mind smarter than all of us combined. The book makes a careful argument for why, with anything remotely like the current state of this field, no one would have any control over what this mind would be or what goals it would have, and humanity will end if it creates a superintelligence. Humanity faces a clear danger of literal extinction caused by AI. This is not an exaggeration; literal deaths of everyone and the end of basically everything of value to us in the universe. And AI companies are in a race to kill everyone. This book is so important because it could help stop humanity on this path to self-annihilation. The book of the day in The Guardian. As The Spectator puts it: "If more and more people understand the danger, wake up and decide to end the “suicide race,” our fate is still in our own hands". Now, a New York Times bestseller. We need to raise the alarm; make the careful case; make it easier for people to be brave to speak up about the danger. While humanity lives, it is still possible for us to stop. To convince the governments to make sure that no one, anywhere, can create a superintelligence until humanity knows how to do that safely. This book can serve as a wake up call for our species. I really hope this is just the beginning.
