on: Rerunning the Time of Perils
I guess my prior coming into this is that non-existential catastrophes are still pretty existentially important, because:
- they are bad in and of themselves
- they are destabilising and make it more likely that we end up with existential catastrophes
  - I definitely wasn’t thinking explicitly about post-ASI catastrophes meaning we’d have to rerun the time of perils
  - But I was thinking about stuff like ‘a big war would probably set back AI development and could also make culture and selection pressures a fair bit worse, such that I feel worse about the outcome of AI development after that’. And similarly for bio
It sounds like your prior was that non-existential catastrophes are much much less important than existential ones, and then these considerations are a big update for you.
So I think part of why I’m less interested in this than you are is just having different priors where this update is fairly small/doesn’t change my prioritisation that much?

in reply to: Will Aldred’s comment on: New 80k problem profile: extreme power concentration
Thanks for the quibble, seems big if true! And agreed it is not something that I was tracking when writing the article.

A few thoughts:
- I am fairly unsure if the economies of scale point is actually right. Some reasons for doubt:
  - Partly I’m thinking of Drexler’s CAIS arguments and intuitions that ecosystems of different specialised systems will outcompete monoculture
  - Partly I’m looking at AI development today
  - Partly the form of the economies of scale argument seems to be ‘one constraint on human economies of scale is coordination costs between humans. So if those are removed, economies of scale will go to infinity!’ But there may well be other trade offs that you reach at higher levels. For example, I’d expect that you lose out on things like creativity/innovation, and that you run higher risks of correlated failures, vulnerabilities etc.
- Assuming it is true, it doesn’t seem like the most important argument within economic dominance to me:
  - The most natural way of thinking about it for me is that AGI increasing economies of scale is a subset of outgrowing the world (where the general class is ‘having better AI enables growing to most of the economy’, and the economies of scale sub-class is ‘doing that via using copies of literally the same AI, such that you get more economies of scale’
  - Put another way, I think the economies of scale thing only leads to extreme power concentration in combination with a big capabilities gap. If lots of people have similarly powerful AI systems, and can use them to figure out that they’d be best off by using a single system to do everything, then I don’t see any reason why one country would dominate. So it doesn’t seem like an independent route to me, it’s a particular form of a route that is causally driven by another factor.
Interested in your takes here!

Thanks for the comment Michael.
A minor quibble is that I think it’s not clear you need ASI to end up with dangerous levels of power concentration, so you might need to ban AGI, and to do that you might need to ban AI development pretty soon.

I’ve been meaning to read your post though, so will do that soon.

in reply to: Emergence101’s comment on: Persistence, Not Projection: The Case for Loop Maintenance over Longtermism
Thanks for your post AJ, and esp this comment which I found clarifying.
I’d be genuinely curious to hear how Cotton-Barratt and Hadshar see this difference. Is it a meaningful distinction? Are these frameworks reconcilable at different scales of analysis? When would we know which better serves long-term flourishing?
I’ve only skimmed your post, and haven’t read what me and Owen wrote in several years, but my quick take is:
- We’re saying ‘within a particular longtermist frame, it’s notable that it’s still rational to allocate resources to neartermist ends, for instrumental reasons’
  - I think you agree with this
  - Since writing that essay, I’m now more worried about AI making humans instrumentally obsolete, in a way that would weaken this dynamic a lot (I’m thinking of stuff like the intelligence curse). So I don’t actually feel confident this is true any more.
- I think you are saying ‘but that is not a good frame, and in fact normatively we should care about some of those things intrinsically’
  - I agree, at least partially. I don’t think we intended to endorse that particular longtermist frame—just wanted to make the argument that even if you have it, you should still care about neartermist stuff. (And actually, caring instrinsically about neartermist stuff is part of what motivated making the argument, iirc.)
  - I vibed with some of your writing on this, e.g. “The Tuesday-morning maintenance network isn’t preparation for a future we’re aiming toward; it is the future, continuously instantiated.”
  - I’m not a straight out yes—I think Wednesday in a million years might matter much more than this Tuesday morning, and am pretty convinced of some aspects of longtermism. But I agree with you in putting intrinsic value on the present moment and people’s experiences in it
So my guess is, you have a fundamental disagreement with some version of longtermism, but less disagreement with me than you thought.

on: A personal take on why you should work at Forethought (maybe)
Thanks Lizka!
Some misc personal reflections:
- Working at Forethought has been my favourite job ever, by a decent margin
- I spent a couple of years doing AI governance research independently/collaborating with others in an ad hoc way before joining Forethought. I think the quality of my work has been way higher since joining (because I’ve been working on more important questions than I was able to make headway on solo), and it’s also been just a huge win in terms of productivity and attention (the costs of tracking my time, hustling for new projects, managing competing projects etc were pretty huge for me and made it really hard to do proper thinking)
One minor addition from me on why/not to work at Forethought: I think the people working at Forethought care pretty seriously about things going well, and are really trying to make a contribution.
I think this is both a really special strength, and something that has pitfalls:
- It’s a privilege to work with people who care in this way, and it cuts a lot of the crap that you’d get in organisations that were more oriented towards short term outcomes, status, etc
- On the other hand, I sometimes worry about Forethought leaning a bit to heavily on EA-style ‘do what’s most impactful’ vibes. I think this can kill curiosity, and also easily degrades into trying to try/people trying to meet their own psychological needs to make an impact instead of really staring in the face the reality we seem to be living in.
  - Other people at Forethought think that we’re not leaning into this enough though: most work on AI futures stuff is low quality and won’t matter at all, and it’s very easy to fill all your time with interesting and pointless stuff. I agree on those failure modes, but disagree about where the right place on the spectrum is.
And then a few notes on the sorts of people I’d be really excited to have apply:
- People who are thinking for themselves and building their own models of what’s going on. I think this is rare and sorely needed. Some particular sub-groups I want to call out:
  - Really smart independent thinkers who want to work on AI macrostrategy stuff but haven’t yet had a lot of surface area with the topic or done a lot of research. I think Forethought could be a great place for someone to soak up a lot of the existing thinking on these topics, en route to developing their own agenda.
  - Researchers with deep world models on the AI stuff, who think that Forethought is kind of wrong/a lot less good than it could be. The high-level aspiration for Forethought is something like, get the world to sensibly navigate the transition to superintelligence. We are currently 6 researchers, with fairly correlated views: of course we are totally failing to achieve this aspiration right now. But it’s a good aspiration, and to the extent that someone has views on how to better address it, I’d love for them to apply.
    If I got to choose one type of researcher to hire, it would be this one.
    My hope would be that for many people in this category, Forethought would be able to ‘get out of the way’: give the person free reign, not entangle them in organisational stuff where they don’t want that, and engage with them intellectually to the extent that it’s mutually productive.
    I agree with Lizka that people who think Forethought sucks probably won’t want to apply/get hired/enjoy working at Forethought.
- People who are working on this stuff already, but hamstrung by not having [a salary/colleagues/an institutional home/enough freedom for research at their current place of work/a manager to support them/etc]. I’d hope that Forethought could be a big win for people in this position, and allow them to unlock a bunch more of their potential.

in reply to: Chris Leong’s comment on: Intelsat as a Model for International AGI Governance
Sorry for the slow response here! Agree that diffusion is an important issue. A few thoughts:
- Some forms of diffusion might be actively good, for reducing concentration of power. So it’s not clear that we want to straightforwardly prevent tech diffusion
- Ways you could reduce tech diffusion within something like Intelsat:
  - Limited membership helps
  - You could do things like require companies it contracts with to comply with strong infosec, require members not to allow frontier development without strong infosec, require member governments to provide gov-level infosec to frontier developers in their countries
  - Intelsat for satellites involved sharing all the technical information. For AGI, it could involve sharing only some forms of information (e.g. weights don’t get shared with everyone, but encrypted chunks of the weights are distributed among founder members)
  - h/t Will: having many countries part of the multilateral project removes their incentives to try to develop frontier AI themselves (and potentially open-source)
