If Anyone Builds it, Everyone Dies review – how AI could kill us all

If machines become superintelligent we're toast, say Eliezer Yudkowsky and Nate Soares. Should we believe them?

What if I told you I could stop you worrying about climate change, and all you had to do was read one book? Great, you'd say, until I mentioned that the reason you'd stop worrying was because the book says our species only has a few years before it's wiped out by superintelligent AI anyway.

We don't know what form this extinction will take exactly - perhaps an energy-hungry AI will let the millions of fusion power stations it has built run hot, boiling the oceans. Maybe it will want to reconfigure the atoms in our bodies into something more useful. There are many possibilities, almost all of them bad, say Eliezer Yudkowsky and Nate Soares in If Anyone Builds It, Everyone Dies, and who knows which will come true. But just as you can predict that an ice cube dropped into hot water will melt without knowing where any of its individual molecules will end up, you can be sure an AI that's smarter than a human being will kill us all, somehow.
