This is the rhetorical trick that LessWrongers (Yudkowsky's site) have settled on for decades: They have justified everything around the premise that there's a chance, however small, that the world will end. You can't argue that the world ending is a bad thing, so they have their opening for the rest of their arguments, which is that we need to follow their advice to prevent the world maybe ending. They rebut any counterarguments by trying to turn it into a P(doom) debate where we're fighting over how likely this outcome is, but by the time the discussion gets there you've already been forced to accept their argument. Then they push the P(doom) argument aside and try to argue that it doesn't matter how unlikely it is, we have a morally duty to act.
A common advantageous strategy is to take the randomly-selected topic, however unrelated, and invent a chain of logic that claims that taking a given side/action leads to an infinitesimal risk of nuclear extinction/massive harms. This results in people arguing that e.g. "building more mass transit networks" is a bad idea because it leads to a tiny increase in the risk of extinction--via chains as silly as "mass transit expansion needs energy, increased energy production leads to more EM radiation, evil aliens--if they exist--are very marginally more likely to notice us due to increased radiation and wipe out the human race". That's not a made-up example.
The strategy is just like the LessWrongers' one: if you can put your opponent in the position of trying to reduce P(doom), you can argue that unless it's reduced to actual zero, the magnitude of the potential negative consequence is so severe as to overwhelm any consideration of its probability.
In competitive debate, this is a strong strategy. Not a cheat-code--there are plenty of ways around it--but common and enduring for many years.
As an aside: "debate", as practiced competitively, often bears little relation to "debate" as understood by the general public. There are two main families of competitive debate: one is more outward-facing and oriented towards rhetorical/communication/persuasion practice; the other is more ingrown and oriented towards persuading other debaters, in debate-community-specific terms, of which side should win. There's overlap, but the two tend to be practiced/judged by separate groups, according to different rubrics, and/or in different spaces or events. That second family is what I'm referring to above.
No one to my knowledge has ever argued that AI research should be prohibited because of a very small probability of its turning out extremely badly. This is entirely a straw man set up by people who want AI research to continue. Yudkowsky argues that if AI research is allowed to continue, then the natural expected outcome will be very bad (probably human extinction, but more exotic terrible outcomes are also possible) [1]. There are others who argue that no team or organization anywhere should engage in any program of development that has a 10% or more chance of ending the human race without there first being an extensive public debate followed by a vote in which everyone can participate, and this is their objection to any continuance of AI research.
[1] But don't take my word for it: here is Yudkowsky writing in Apr 2022 in https://www.lesswrong.com/posts/j9Q8bRmwCgXRYAgcJ/: "When Earth’s prospects are that far underwater in the basement of the logistic success curve, it may be hard to feel motivated about continuing to fight, since doubling our chances of survival will only take them from 0% to 0%. That's why I would suggest reframing the problem - especially on an emotional level - to helping humanity die with dignity, or rather, since even this goal is realistically unattainable at this point, die with slightly more dignity than would otherwise be counterfactually obtained."
Can't you? Haven't many (most?) countries agreed to nuclear disarmament? What about biological weapons? Even anti-personnel mines, I think?
That kind of idea might have held water in the 90's, but that's not the world we live in any longer.
This misses the point. He specifically said the entire world because the point is that someone will develop AGI (theoretically; I’m not making a statement about how close we are to this).
9 nations have nuclear weapons despite non proliferation agreements and supposed disarmament. It’s not enough for most countries to agree not to build nuclear weapons if the goal is to have no nuclear weapons. Same for AGI. If it can be developed, you need all nations to agree not to develop it if it don’t want it to exist. Otherwise it will simply be developed by nations that don’t agree with you.
(Also arguably the only reason most nations don’t have nuclear weapons is the threat of destruction from nations that already have them if they try.)
I wish they did before too.
I don't remember who, but someone made an interesting point about this around the time GPT-4 was released: If the major nuclear powers all understand this, doesn't that make nuclear war more likely the closer any of them get to AGI/ASI? After all, if the other side getting there first guarantees the complete and total defeat of one's own side, a leader may conclude that they don't have anything to lose anymore and launch a nuclear first strike. There are a few arguments for why this would be irrational (e.g. total defeat may, in expectation, be less bad than mutual genocide), but I think it's worth keeping in mind as a possibility.
Nuclear weapon proliferation seems to have plateaued recently, but I think that this appearance is partly deceptive. The main reasons it has plateaued is that: 1) building and maintaining nuclear weapons is expensive, 2) there are powerful countries that are willing to use military force to stop some other countries from developing nukes, and 3) many countries have reached nuclear latency (the ability to build nuclear weapons very quickly once the political order is given to do it) and are only avoiding actually giving the order to build nukes because they don't see a current important-enough reason to do it.
The prohibitions aren't perfect, of course (and not without their own negative externalities in some cases). But all of those things are much more accessible to people than nuclear weapons, and we've still had successes in banning/reducing them. So maybe there's hope yet.
