(edit: status: not a crux, instead downstream of different beliefs about what the first safe ASI will look like in predicted futures where it exists. If I instead believed 'task-aligned superintelligent agents' were the most feasible form of pivotally useful AI, I would then support their use for pivotal acts.)
I was rereading some of the old literature on alignment research sharing policies after Tamsin Leake's recent post and came across some discussion of pivotal acts as well.
Hiring people for your pivotal act project is going to be tricky. [...] People on your team will have a low trust and/or adversarial stance towards neighboring institutions and collaborators, and will have a hard time forming good-faith collaboration. This will alienate other institutions and make them not want to work with you or be supportive of you.
This is in a context where the 'pivotal act' example is using a safe ASI to shut down all AI labs.[1]
My thought is that I don't see why a pivotal act needs to be that. I don't see why shutting down AI labs or using nanotech to disassemble GPUs on Earth would be necessary. These may be among the 'most direct' or 'simplest to imagine' possible actions, but in the case of superintelligence, simplicity is not a constraint.
We can instead select for the 'kindest' or 'least adversarial' or actually: functional-decision-theoretically optimal actions that save the future while minimizing the amount of adversariality this creates in the past (present).
Which can be broadly framed as 'using ASI for good'. Which is what everyone wants, even the ones being uncareful about its development.
Capabilities orgs would be able to keep working on fun capabilities projects in those days during which the world is saved, because a group following this policy would choose to use ASI to make the world robust to the failure modes of capabilities projects rather than shutting them down. Because superintelligence is capable of that, and so much more.
side note: It's orthogonal to the point of this post, but this example also makes me think: if I were working on a safe ASI project, I wouldn't mind if another group who had discreetly built safe ASI used it to shut my project down, since my goal is 'ensure the future lightcone is used in a valuable, tragedy-averse way' and not 'gain personal power' or 'have a fun time working on AI' or something. In my morality, it would be naive to be opposed to that shutdown. But to the extent humanity is naive, we can easily do something else in that future to create better present dynamics (as the maintext argues).
If there is a group for whom using ASI to make the world robust to risks and free of harm, in a way where its actions don't infringe on ongoing non-violent activities is problematic, then this post doesn't apply to them as their issue all along was not with the character of the pivotal act, but instead possibly with something like 'having my personal cosmic significance as a capabilities researcher stripped away by the success of an external alignment project'.
Another disclaimer: This post is about a world in which safely usable superintelligence has been created, but I'm not confident that anyone (myself included) currently has a safe and ready method to create it with. This post shouldn't be read as an endorsement of possible current attempts to do this. I would of course prefer if this civilization were one which could coordinate such that no groups were presently working on ASI, precluding this discourse.
See minimality principle:
the least dangerous plan is not the plan that seems to contain the fewest material actions that seem risky in a conventional sense, but rather the plan that requires the least dangerous cognition from the AGI executing it
