Thanks for clarifying. Here’s my main criticism of your principle.
Without additional information about expected utility of any given element
, I can say [its expected utility is negative.]
I basically agree with this. If all you know about an action is that it belongs to a set of actions with presumed independent effects that add up to negative value, then the expected value of that action is negative.
However, you usually have additional information about the action, so the argument doesn’t apply. So your principle is very weak.
I think this is the answer to your question at the top of this thread: Why do people concerned about catastrophic risks from AI sometimes do things in the direction of supporting AI? Because they know the details of the particular actions they’re taking, and based on those details they judge those actions to have positive expected value. (Ideally! Many people are nincompoops who do things for bad reasons. But I think the Unslop contest was fine.) That’s why I said “you have to disagree on the numbers”.
I think you tend to use a stronger version of the principle which is something like, “Come on, there’s no way you have enough information to know that it’s positive expected value, something funny is going on.” To which I would say, “No really, let’s talk about the numbers, it checks out.”
I’m running out of energy to spend on this thread, though.
Now we’re getting somewhere. You’re assuming that providing one billionth of this year’s investment in AI means decreasing the expected utility from human extinction by one billionth. But that’s not right. If you invest in AI, that means the AI companies will choose to raise less money from other investors. The net effect is that AI companies will raise a little more money than if you hadn’t invested (but less than the amount you invest), get a better interest rate, and spend less effort on fundraising this year. And this will have some effect on the probability of an extinction-level AI catastrophe this generation, but the effect isn’t linear in the amount you invest.
In a parallel thread, your theory of impact was that divestment has an effect on regulation. That’s also nonlinear.
Investing in AI is something I’m likely to do. (Arguably >10% of the S&P 500 by market cap use marginal investment to try to build frontier models.) Here’s how I justify it: The amount of stock I can buy won’t move the stock price perceptibly. If I estimated the price movement it would be tiny. That would translate into AI companies expending a tiny bit less effort on selling stock this year to fund datacenters, which accelerates timelines a little bit, which increases existential risk a very tiny amount. On the other hand, if I invest my savings in a broad-market index fund that includes AI, that’ll increase my savings and I’ll have more time to spend doing AI safety research, calling my Congressperson, etc., which are more directly impactful. Plus, I have lots of personal uses for more money.
I’m basically satisfied with where this thread ended up. (I just wanted to convey that it’s in general reasonable to do things that seem individually worth it, even if they seem to be promoting AI in some way.) I want to flag that I won’t have the energy to find a crux in our disagreement over the Unslop contest or whether I should buy index funds. Though if you have a good argument about why not to buy index funds I haven’t thought of, I’ll be interested to hear that.
