Announcing a contest: EA Criticism and Red Teaming
As Buck points out, Toby’s estimate of P(AI doom) is closer to the ‘mainstream’ than MIRI’s, and close enough that “so low” doesn’t seem like a good description.
I can’t really speak on behalf of others at FHI, of course, by I don’t think there is some ‘FHI consensus’ that is markedly higher or lower than Toby’s estimate.
Also, I just want to point out that Toby’s 1⁄10 figure is not for human extinction, it is for existential catastrophe caused by AI, which includes scenarios which don’t involve extinction (forms of ‘lock-in’). Therefore his estimate for extinction caused by AI is lower than 1⁄10.
Effective Ideas is announcing a $100,000 blog prize
Yes, I’m almost certain it’s too ‘galaxy brained’! But does the case rely on entities outside our light cone? Aren’t there many ‘worlds’ within our light cone? (I literally have no idea, you may be right, and someone who knows should intervene)
I’m more confident that this needn’t relate to the literature on infinite ethics, since I don’t think any of this relies on inifinities.
Thanks, this is useful.
There are some interesting and tangentially related comments in the discussion of this post (incidentally, the first time I’ve been ‘ratioed’ on LW).
Thanks, really appreciate it!
Was wondering the same thing — would it be possible to set others’ answers as hidden by default on a post until the reader makes a prediction?
I interviewed Kent Berridge a while ago about this experiment and others. If folks are interested, I wrote something about it here, mostly trying to explain his work on addiction. You can listen to the audio on the same page.
Got it, thanks very much for explaining.
Thanks, that’s a nice framing.
Thanks for the response. I’m bumping up against my lack of technical knowledge here, but a few thoughts about the idea of a ‘measure of existence’ — I like how UDASSA tries to explain how the Born probabilities drop out of a kind of sampling rule, and why, intuitively, I should give more ‘weight’ to minds instantiated by brains rather than a mug of coffee. But this idea of ‘weight’ is ambiguous to me. Why should sampling weight (you’re more likely to find yourself as a real vs Boltzmann brain, or ‘thick’ vs ‘arbitrary’ computation) imply ethical weight (the experiences of Boltzmann brains matter far less than real brains)? Here’s Lev Vaidman, suggesting it shouldn’t: “there is a sense in which some worlds are larger than others”, but “note that I do not directly experience the measure of my existence. I feel the same weight, see the same brightness, etc. irrespectively of how tiny my measure of existence might be.” So in order to think that minds matter in proportion to the mesaure of the world they’re in, while recognising they ‘feel’ precisely the same, it looks like you end up having to say that something beyond what a conscious experience is subjectively like makes an enormous difference to how much it matters morally. There’s no contradiction, but that seems strange to me — I would have thought that all there is to how much a conscious experience matters is just what it feels like — because that’s all I mean by ‘conscious experience’. After all, if I’m understanding this right, you’re in a ‘branch’ right now that is many orders of magnitude less real than the larger, ‘parent’ branch you were in yesterday. Does that mean that your present welfare now matters orders of magnitude less than yesterday? Another approach might be to deny that arbitrary computations are conscious on independent grounds, and explain the observed Born probabilities without ‘diluting’ the weight of future experiences over time.
Also, presumably there’s some technical way of actually cashing out the idea of something being ‘less real’? Literally speaking, I’m guessing it’s best not to treat reality as a predicate at all (let alone one that comes in degrees). But that seems like a surmountable issue.
I’m afraid I’m confused by what you mean about including the Hilbert measure as part of the definition of MWI. My understanding was that MWI is something like what you get when you don’t add a collapse postulate, or any other definitional gubbins at all, to the bare formalism.
Still don’t know what to think about all this!
More Notes
Something very like the view I’m suggesting can be found in Albert & Loewer (1988) and their so-called ‘many minds’ interpretation. This is interesting to read about, but the whole idea strikes me as extremely hand-wavey and silly. Here’s David Wallace with a dunk: “If it is just a fundamental law that consciousness is associated with some given basis, clearly there is no hope of a functional explanation of how consciousness emerges from basic physics.”
I should also mention that I tried explaining this idea to another philosopher of physics, who took it as a reductio of MWI! I suppose you might also take it as a reductio of any kind of total consequentialism also. One man’s modus ponens...
David Lewis briefly discusses the ethical implications of his modal realism (warning: massive pdf), concluding that there aren’t any. This may be of interest, but not sufficiently similar to the case at hand to be directly relevant, I think.
Another potential ethical implication: Hal Finney makes the point that MWI should steer you towards maximising good outcomes in expectation if you weren’t already doing so (e.g. if you were previously risk-averse, risk-seeking, or just somehow insensitive to very small probabilities of extreme outcomes). The whole thread is a nice slice of LW history and worth reading.
Ethics in Many Worlds
Thanks, that’s far more relevant!
There are some social reasons for writing and reading blogs.
One reason is that “a blog post is a very long and complex search query to find fascinating people and make them route interesting stuff to your inbox”. I expect to continue to value finding new people who share my interests after AI starts writing better blog posts than me, which could be very soon. I’m less sure about whether this continues to be a good reason to write them, since I imagine blog posts will become a less credible signal of what I’m like.
Another property that makes me want to read a blog or blogger is the audience: I value that it’s likely my peers will also have read what I’m reading, so I can discuss it. This gives the human bloggers some kind of first-mover advantage, because it might only be worth switching your attention to the AI bloggers if the rest of the audience coordinates to switch with you. Famous bloggers might then switch into more of a curation role.
To some extent I also intrinsically care about reading true autobiography (the same reason I might intrinsically care about watching stunts performed by real humans, rather than CGI or robots).
I think these are relatively minor factors, though, compared to the straightforward quality of reasoning and writing.
