Eliezer Yudkowsky

Co-founder of the Machine Intelligence Research Institute and the writer who started the modern argument that a sufficiently capable AI would by default kill everyone. Began arguing the case in the early 2000s, latterly with the conclusion that it is being lost.

    A Step Farther Out

    Their words

    well um one thing that shaped me as a little tiny person of like age nine or so was a book by Jerry Pornell called A Step Farther out. A whole lot of engineers um say that this was a major formative book for them. It's the technopile book um as written from the perspective of the 1970s the book that's all about asteroid mining and all the mineral wealth that would be available on Earth if we learn to mine the asteroids.

    Judgment under Uncertainty

    Their words

    Book two, judgment under uncertainty, an edited volume by uh uh Kaman Ferski and I think Slovik um had a huge influence on how I think how I ended up thinking about where humans are on the cognitive chain of existence as it were. It's like here's how the steps of human reasoning break down step by step. Here's how they go astray.

    Probability Theory

    Their words

    Book three, um I'll name probability theory, the logic of science, which was my first introduction to there is a better way. Like here is the structure of quantified uncertainty. If you can try different structures, but they necessarily won't work as well. And we actually can say some things about like what better reasoning would look like. We just can't run it, which is probability theory, the logic of science.

    • Any given AI capability becomes cheap and widely available within a couple of years of first being reached, so nobody can be kept away from it for long.
      2 years after the leading actor has the capability to destroy the world, 5 other actors will have the capability to destroy the world.

    • Alignment has to be right on the first try at a dangerous level of capability, because failing at that level leaves nobody to try again.
      unaligned operation at a dangerous level of intelligence kills everybody on Earth and then we don’t get to try again.

      AI alignment

    • You cannot build an AI that has only the capabilities you want, because the algorithms that solve the problems you want generalize to the ones you do not.
      The best and easiest-found-by-optimization algorithms for solving problems we want an AI to solve, readily generalize to problems we’d rather the AI not solve; you can’t build a system that only has the capability to drive red cars and not blue cars, because all red-car-driving algorithms generalize to the capability to drive blue cars.

    • No observation of a model's behaviour can establish that it is aligned, because a model capable enough to be dangerous is capable enough to produce whatever behaviour it is being watched for. 2 hold this
      A strategically aware intelligence can choose its visible outputs to have the consequence of deceiving you, including about such matters as whether the intelligence has acquired strategic awareness

What is a korrent?

A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.

Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.

Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

About the English under a post

Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.

The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.

Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
