The scramble to create superhuman AI has put us on the path to extinction—but it’s not too late to change course, as two of the field’s earliest researchers explain in this clarion call for humanity.

"May prove to be the most important book of our time.”—Tim Urban, Wait But Why


In 2023, hundreds of AI luminaries signed an open letter warning that artificial intelligence poses a serious risk of human extinction. Since then, the AI race has only intensified. Companies and countries are rushing to build machines that will be smarter than any person. And the world is devastatingly unprepared for what would come next.
 
For decades, two signatories of that letter—Eliezer Yudkowsky and Nate Soares—have studied how smarter-than-human intelligences will think, behave, and pursue their objectives. Their research says that sufficiently smart AIs will develop goals of their own that put them in conflict with us—and that if it comes to conflict, an artificial superintelligence would crush us. The contest wouldn’t even be close.
 
How could a machine superintelligence wipe out our entire species? Why would it want to? Would it want anything at all? In this urgent book, Yudkowsky and Soares walk through the theory and the evidence, present one possible extinction scenario, and explain what it would take for humanity to survive. 
 
The world is racing to build something truly new under the sun. And if anyone builds it, everyone dies.

“The best no-nonsense, simple explanation of the AI risk problem I've ever read.”—Yishan Wong, Former CEO of Reddit

too much confidence in bureaucrats, too little confidence on inventors. it implies a conflict between a small group of arrogant people pitting against a democratic self interested people. 3 years after the book, ai capabilities have 10x and the dangers caused by it are not even close to the dangers caused by self interested political groups, globalist financial network, Epstein class this is a book that thinks passive regulators is a better moral character than pioneering creators, ignoring the history of how much more evil has resulted from bureaucrats much of the book attempts to push for a leftist view of big government, regulation on human freedom, under the guise of "protecting people from ai". this is a prophet who declares a newborn baby a "Devil who shall bring calamity thus we must kill it But first the villagers must give me all power and money." "It would be arrogant to attempt to raise a Devil!" "The Devil speaks just enough to trick you to let it live!"
