If Anyone Builds It, Everyone Dies

Why Superhuman AI Would Kill Us All

De: Eliezer Yudkowsky, Nate Soares

Narrado por: Rafe Beckley

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

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.

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.

Reseñas de la Crítica

“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, fueled by wishful thinking."—Max Tegmark, author of Life 3.0: Being Human in the Age of AI

“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, cofounder, Wait But Why

Everyone needs to read this book.

You may read this book, and find that you don't completely agree with it. That is ok. I would be shocked however, if you somehow read this book and felt that the current state of affairs around AI development is acceptable.

Everyone should be able to agree, given the points made in this book, that the current state of AI development is reckless. This is the Silent Spring of the 21st century, and we have far less time to react. Even if you are familiar with the topic, reading the book and the accompanying online resources will probably bring to the forefront just how dangerous and critical of an issue this is.

Extinction risk is not fun to think about, but it's important we do think about it.

This book lays out the case brilliantly, and might even motivate you to action in whatever way you can contribute to make disaster that little bit less likely.

Might turn out to be the most important book of our time

Here is my highly-condensed version of the book's argument, which I find convincing.

We are a long way off from solving what's known as the alignment problem.

If anyone released artificial superindulgence into the world using anything like our current process, it would almost certainly be misaligned with The interests of humankind.

Artificial super intelligence would have the capability to radically alter, and even extinguish human (and all) life on Earth.

Once it had been released, we would not be able to stop it, contain it, or fix it should it decide to hurt us (or do anything we don't like).

We are moving towards super intelligence with reckless abandon, rather than an appropriate sense of caution.

Since we don't know how close we are to achieving super intelligence, the only reasonable way to reduce the existential threat is to globally pause research towards super intelligence.


I sincerely hope this book fuels the global discussions on AI safety.

The vision

Wow !!! This changed my mind on this and I am a definite convert! Elegantly written.

This book scared me, but I should be scared. We all should be.

The author did an excellent job of laying out how AI is "grown", in a way that the layperson can make sense of it. The book does an even better job of illustrating how a truly 'alien' intellect would differ from us, and how this is what we would be facing with ASI. We only get one chance to get it wrong...

Excellent distillation of the perils of sleepwalking into an AI future!

This work had excellent information about the workings of LLMs that I had not been aware of previously. It is engaging and does an excellent job explaining and illustrating the principles, arguments, and conclusions the author are seeking to convey. It is also terrifying and confounding, but offers a glimmer of hope. There is much to fear if you take this work as seriously as it should be. However, there is also a chance to hear the warning and take action.

If people get this book it’s the most important book in the history of the known universe.

This book, although written by a couple of hard core tech and science nerds, makes the case as clear for none techies as someone with their background can likely hope to make it. The message is clear stark and delivered in plain language, and never shy away from either the dangerous situation we are approaching and why we need to change our path if we want to survive. It does not claim that it is in any way easy to avoid extinction brought about by someone building superhuman AGI, but it does explain what a realistic paths towards avoiding such extinction could look like and it gives examples from history of how humanity has successfully avoided catastrophy through cooperation. Every leader of every nation, minister or member of parliament should read this book. Every big tech CEO should read it. Every earthling should read it. If enough people understand this message in time, we still have a chance for new generations of humans and life on earth to survive and flourish into the future.

This book if read and understood and taken with the seriousness it deserves, could turn out to be more important than the Bible, the Quran, the Veda, Principia, Wealth of Nations, Das Kapital combined.

So much to learn in book

Knowing at least moved my mind from worrying about politics😂 seriously - I thought our brains turning to mush and unemployment were our only risks - there is so much more. Simple stories accompany all technical explanations.

Excellent explainer for the most important problem

The title is not an exaggeration. This is a short and accessible explanation of the most important problem in the world: the threat of extinction from superintelligent AI.

This book came out today. I started reading this morning and finished this afternoon. I was excited to read it, to say the least, and Yudkowsky and Soares didn't disappoint.

If you don't think AI is the biggest threat facing humanity, read this book. If you do, buy copies for your friends and family. Let's hope the authors are wrong and fight as if they're right.

Everyone should listen to this

This audiobook gives a clear and concise outline of the most important issue facing our generation. An uncomfortable truth is no less true
