If Anyone Builds It, Everyone Dies

The Case Against Superintelligent AI

  • Eliezer Yudkowsky and Nate Soares




The founder of the field of AI risk explains why superintelligent AI is a global suicide bomb and we must halt development immediately

AI is the greatest threat to our existence that we have ever faced.

The scramble to create superhuman AI has put us on the path to extinction – but it’s not too late to change course. Two pioneering researchers in the field, Eliezer Yudkowsy and Nate Soares, explain why artificial superintelligence would be a global suicide bomb and call for an immediate halt to its development.

The technology may be complex, but the facts are simple: companies and countries are in a race to build machines that will be smarter than any person, and the world is devastatingly unprepared for what will come next.

How could a machine superintelligence wipe out our entire species? Will it want to? Will it want anything at all? In this urgent book, Yudkowsky and Soares explore 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 – and if anyone builds it, everyone dies.

Praise for If Anyone Builds It, Everyone Dies

The most important book I’ve read for years: I want to bring it to every political and corporate leader in the world and stand over them until they’ve read it. Yudkowsky and Soares, who have studied AI and its possible trajectories for decades, sound a loud trumpet call to humanity to awaken us as we sleepwalk into disaster. Their brilliant gift for analogy, metaphor and parable clarifies for the general reader the tangled complexities of AI engineering, cognition and neuroscience better than any book on the subject I’ve ever read, and I’ve waded through scores of them. We really must rub our eyes and wake the fuck up!

Stephen Fry

If Anyone Builds It, Everyone Dies may prove to be the most important book of our time. Yudkowsky and Soares believe we are nowhere near ready to make the transition to superintelligence safely, leaving us on the fast track to extinction. Through the use of parables and crystal-clear explainers, they convey their reasoning, in an urgent plea for us to save ourselves while we still can

Tim Urban, co-founder of Wait But Why

The best no-nonsense, simple explanation of the AI risk problem I've ever read

Yishan Wong, former CEO of Reddit

Soares and Yudkowsky lay out, in plain and easy-to-follow terms, why our current path toward ever-more-powerful AIs is extremely dangerous

Emmett Shear, former interim CEO of OpenAI

The most important book of the decade ... This captivating page-turner, from two of today's clearest thinkers, reveals that the competition to build smarter-than-human machines isn't an arms race but a suicide race, fuelled by wishful thinking

Max Tegmark, author of Life 3.0

An eloquent and urgent plea for us to step back from the brink of self-annihilation

Fiona Hill, Defence Advisor to UK government

Everyone should read this book. I’m 70% confident that you – yes, you reading this right now – will one day grudgingly admit that we all should have listened to Yudkowsky and Soares when we still had the chance

Daniel Kokotajlo, OpenAI whistleblower and lead author, AI 2027

A fire alarm ringing with clarity and urgency. Yudkowsky and Soares pull no punches

Mark Ruffalo

A compelling introduction to the world's most important topic. Artificial general intelligence could be just a few years away. This is one of the few books that takes the implications seriously, published right as the danger level begins to spike

Scott Alexander, founder of Astral Codex Ten

Claims about the risks of AI are often dismissed as advertising, but this book disproves it. Yudkowsky and Soares are not from the AI industry, and have been writing about these risks since before it existed in its present form. Read their disturbing book and tell us what they get wrong

Huw Price, Professor of Philosophy, University of Cambridge

This book offers brilliant insights into history’s most consequential standoff between technological utopia and dystopia, and shows how we can and should prevent superhuman AI from killing us all. Yudkowsky and Soares’s memorable storytelling about past disaster precedents ... highlights why top thinkers so often don't see the catastrophes they create

George Church, Professor of Genetics, Harvard University

Silicon Valley calls it inevitable. Your survival instinct knows better. Humanity is funding its own delete key - an unblinking intelligence that never sleeps, never stops, perfectly indifferent. Wonder-time is over; this is our warning. Read today. Circulate tomorrow. Demand the guardrails. I’ll keep betting on humanity, but first we must wake up

R.P. Eddy, former director, White House, National Security Council

You will feel actual emotions when you read this book. We are currently living in the last period of history where we are the dominant species. Humans are lucky to have Soares and Yudkowsky in our corner, reminding us not to waste the brief window of time that we have to make decisions about our future in light of this fact

Grimes

A timely and terrifying education on the galloping havoc AI could unleash - unless we grasp the reins and take control

Kirkus

A clearly written and compelling account of the existential risks that highly advanced AI could pose to humanity

Ben Bernanke, Nobel Prize winner in economics

A sober but highly readable book on the very real risks of AI. Both sceptics and believers need to understand the authors’ arguments, and work to ensure that our AI future is more beneficial than harmful

Bruce Schneier, author of A Hacker's Mind

You’re likely to close this book fully convinced that governments need to shift immediately to a more cautious approach to AI, an approach more respectful of the civilization-changing enormity of what's being created. I’d like everyone on earth who cares about the future to read this book and debate its ideas

Scott Aaronson, Professor and Chair of Computer Science, University of Texas at Austin

[An] urgent clarion call to prevent the creation of artificial superintelligence … A frightening warning that deserves to be reckoned with
