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

A fascinating concept bogged down by sensationalist, poorly crafted explanations of people who have been in the industry too long to communicate with the layperson this book is targeting. Often the anecdotes will spend a large amount of time belaboring a point, trying to evoke emotion and anthropomorphization to something that should be a definite statement of observable fact. This book was recommended from an interview, where both author and interviewer were explicit in avoiding prescribing philosophy and emotion to AI, sticking to observable fact, but the book has no such qualms.

An important message from intelligent minds. This book describes for the lay person how AI (probably) will end us. It was a tad repetitive though. Sometimes felt like every chapter had the same paragraph.

This was clearly not written by writers but by researchers who are desperately trying to sound alarm bells. This isn't about the existential threats to the economy, the education system, human relationships, information systems, cyber security, and the acceleration of extraction of resources and every from the planet that AI portends. There are other books for that. This is about the direct risks that we face with an artificial superintelligence and the likely ways that humanity may be intentionally or accidentally largely destroyed as a result of its rise. I do not recommend reading this for your mental health. But if you want to understand why so many AI security researchers and executives are quitting and sounding alarms, this is the book for you.

About the author

ELIEZER YUDKOWSKY is one of the founding researchers of the field of AGI alignment, which is concerned with understanding how smarter-than-human intelligences think, behave, and pursue their goals.  He appeared on TIME magazine’s list of the 100 Most Influential People In AI, was one of the twelve public figures featured in The New York Times’s “Who’s Who Behind the Dawn of the Modern Artificial Intelligence Movement,” and was one of the seven thought leaders spotlighted in The Washington Post’s discussion of “AI’s Rival Factions.”  He spoke on the main stage at 2023’s TED conference and has been discussed or interviewed in The New Yorker, Newsweek, Forbes, Wired, Bloomberg, The Atlantic, The Economist, and many other venues.  He has close to 200,000 followers on X, where he frequently dialogues with prominent public figures including the heads of frontier AI labs.
 
NATE SOARES is the President of MIRI. He has been working in the field for over a decade, after previous experience at Microsoft and Google. Soares is the author of a large body of technical and semi-technical writing on AI alignment, has been interviewed in Vanity Fair and the Financial Times, and has spoken on conference panels alongside many of the AI field’s leaders.
