I like the thrust of this paper, but I feel that it overstates how robust the safety properties will be, by drawing an overly sharp distinction between agentic and non-agentic systems, and not really engaging with the strongest counterexamples
To give some examples from the text:
A chess-playing AI, for instance, is goal-directed because it prefers winning to losing. A classifier trained with log likelihood is not goal-directed, as that learning objective is a natural consequence of making observations
But I could easily train an AI which simply classifies chess moves by quality. What takes that to being an agent is just the fact that its outputs are labelled as 'moves' rather than as 'classifications', rather than any feature of the model itself. More generally, even a LM can be viewed as "merely" predicting next tokens -- the fact that there is some perspective from which a system is non-agentic does not actually tell us very much.
Paralleling a theoretical scientist, it only generates hypotheses about the world and uses them to evaluate the probabilities of answers to given questions. As such, the Scientist AI has no situational awareness and no persistent goals that can drive actions or long-term plans.
I think it's a stretch to say something generating hypotheses about the world has no situational awareness and no persistent goals -- maybe it has indexical uncertainty, but a sufficiently powerful system is pretty likely to hypothesise about itself, and the equivalent of persistent goals can easily fall out of any ways its world model doesn't line up with reality. Note that this doesn't assume the AI has any 'hidden goals' or that it ever makes inaccurate predictions.
I appreciate that the paper does discuss objections to the safety of Oracle AIs, but the responses also feel sort of incomplete. For instance:
Overall, I'm excited by the direction, but it doesn't feel like this approach actually gets any assurances of safety, or any fundamental advantages.
Thank you for the very detailed comment! I’m pretty sympathetic to a lot of what you’re saying, and mostly agree with you about the three properties you describe. I also think we ought to do some more spelling-out of the relationship between gradual disempowerment and takeover risk, which isn’t very fleshed-out in the paper — a decent part of why I’m interested in it is because I think it increases takeover risk, in a similar but more general way to the way that race dynamics increase takeover risk.
I’m going to try to respond to the specific points you lay out, probably not in enough detail to be super persuasive but hopefully in a way that makes it clearer where we might disagree, and I’d welcome any followup questions off the back of that. (Note also that my coauthors might not endorse all this.)
Responding to the specific assumptions you lay out:
Overall, I think I can picture worlds where (conditional on no takeover) we reach states of pretty serious disempowerment of the kind described in the paper, without any of these assumptions fully breaking down. That said, I expect AI rights to be the most important, and the one that starts breaking down first.
As for the feedback loops you mention:
I hope this sheds some light on things!
The writing here was definitely influenced by Lewis (we quote TAoM in footnote 6), although I think the Choice Transition is broader and less categorically negative.
For instance in Lewis's criticism of the potential abolition he writes things like:
The old dealt with its pupils as grown birds deal with young birds when they teach them to fly; the new deals with them more as the poultry-keeper deals with young birds— making them thus or thus for purposes of which the birds know nothing. In a word, the old was a kind of propagation—men transmitting manhood to men; the new is merely propaganda.
The Choice Transition as we're describing it is consistent with either of these approaches. There needn't be any ruling minority, nor do we assume humans can perfectly control future humans, just that they (or any other dominant power) can appropriately steer emergent inter-human dynamics (if there are still humans).
Could you expand on what you mean by 'less automation'? I'm taking it to mean some combination of 'bounding the space of controller actions more', 'automating fewer levels of optimisation', 'more of the work done by humans' and maybe 'only automating easier tasks' but I can't quite tell which of these you're intending or how they fit together.
(Also, am I correctly reading an implicit assumption here that any attempts to do automated research would be classed as 'automated ai safety'?)
When I read this post I feel like I'm seeing four different strands bundled together:
1. Truth-of-beliefs as fuzzy or not
2. Models versus propositions
3. Bayesianism as not providing an account of how you generate new hypotheses/models
4. How people can (fail to) communicate with each other
I think you hit the nail on the head with (2) and am mostly sold on (4), but am sceptical of (1) - similar to what several others have said, it seems to me like these problems don't appear when your beliefs are about expected observations, and only appear when you start to invoke categories that you can't ground as clusters in a hierarchical model.
That leaves me with mixed feelings about (3):
- It definitely seems true and significant that you can get into a mess by communicating specific predictions relative to your own categories/definitions/contexts without making those sufficiently precise
- I am inclined to agree that this is a particularly important feature of why talking about AI/x-risk is hard
- It's not obvious to me that what you've said above actually justifies knightian uncertainty (as opposed to infrabayesianism or something), or the claim that you can't be confident about superintelligence (although it might be true for other reasons)
Strongly agree that active inference is underrated both in general and specifically for intuitions about agency.
I think the literature does suffer from ambiguity over where it's descriptive (ie an agent will probably approximate a free energy minimiser) vs prescriptive (ie the right way to build agents is free energy minimisation, and anything that isn't that isn't an agent). I am also not aware of good work on tying active inference to tool use - if you know of any, I'd be pretty curious.
I think the viability thing is maybe slightly fraught - I expect it's mainly for anthropic reasons that we mostly encounter agents that have adapted to basically independently and reliably preserve their causal boundaries, but this is always connected to the type of environment they find themselves in.
For example, active inference points to ways we could accidentally build misaligned optimisers that cause harm - chaining an oracle to an actuator to make a system trying to do homeostasis in some domain (like content recommendation) could, with sufficient optimisation power, create all kinds of weird and harmful distortions. But such a system wouldn't need to have any drive for boundary preservation, or even much situational awareness.
So essentially an agent could conceivably persist for totally different reasons, we just tend not to encounter such agents, and this is exactly the kind of place where AI might change the dynamics a lot.
Interesting! I think one of the biggest things we gloss over in the piece in how perception fits into the picture, and this seems like a pretty relevant point. In general the space of 'things that give situational awareness' seems pretty broad and ripe for analysis.
I also wonder how much efficiency gets lost by decoupling observation and understanding - at least in humans, it seems like we have a kind of hierarchical perception where our subjective experience of 'looking at' something has already gone through a few layers of interpretation, giving us basically no unadulterated visual observation, presumably because this is more efficient (maybe in particular faster?).
This seems like a misunderstanding / not my intent. (Could you maybe quote the part that gave you this impression?)
I believe Dusan was trying to say that davidad's agenda limits the planner AI to only writing provable mathematical solutions. To expand, I believe that compared to what you briefly describe, the idea in davidad's agenda is that you don't try to build a planner that's definitely inner aligned, you simply have a formal verification system that ~guarantees what effects a plan will and won't have if implemented.
Ah I should emphasise, I do think all of these things could help -- it definitely is a spectrum, and I would guess these proposals all do push away from agency. I think the direction here is promising.
The two things I think are (1) the paper seems to draw an overly sharp distinction between agents and non-agents, and (2) basically all of the mitigations proposed look like they break down with superhuman capabilities. Hard to tell which of this is actual disagreements and which is the paper trying to be concise and approachable, so I'll set that aside for now.
It does seem like we disagree a bit about how likely agents are to emerge. Some opinions I expect I hold more strongly than you:
