Why are you a realist about the Solomonoff prior instead of treating it as a purely theoretical construct?
A theory of embedded world-modeling would be an improvement over current predictive models of advanced AI behavior, but it wouldn't be the whole story. Game theory makes dualistic assumptions too (e.g., by treating the decision process as not having side effects), so we would also have to rewrite it into an embedded model of motivation.
Cartesian frames are one of the few lines of agent foundations research in the past few years that seem promising, due to allowing for greater flexibility in defining agent-environment boundaries. Preferably, we would have a model that lets us avoid having to postulate an agent-environment boundary at all. Combining a successor to Cartesian frames with an embedded theory of motivation, likely some form of active inference, might give us an accurate overarching theory of embedded behavior.
And this is where the fundamental AGI-doom arguments – all these coherence theorems, utility-maximization frameworks, et cetera – come in. At their core, they're claims that any "artificial generally intelligent system capable of autonomously optimizing the world the way humans can" would necessarily be well-approximated as a game-theoretic agent. Which, in turn, means that any system that has the set of capabilities the AI researchers ultimately want their AI models to have, would inevitably have a set of potentially omnicidal failure modes.
This is my crux with people who have 90+% P(doom): will vNM expected utility maximization be a good approximation of the behavior of TAI? You argue that it will, but I expect that it won't.
My thinking related to this crux is informed less by the behaviors of current AI systems (although they still influence it to some extent) than by the failure of the agent foundations agenda. The dream 10 years ago was that if we started by modeling AGI as an vNM expected utility maximizer, and then gradually added more and more details to our model to account for differences between the idealized model and real-world AI systems, we would end up with an accurate theoretical system for predicting the behaviors AGI would exhibit. It would be a similar process to how physicists start with an idealized problem setup and add in details like friction or relativistic corrections.
But that isn't what ended up happening. Agent foundations researchers ended up getting stuck on the cluster of problems collectively described as embedded agency, unable to square the dualistic assumptions of expected utility theory and Bayesianism with the embedded structure of real-world AI systems. The sub-problems of embedded agency are many and too varied to allow one elegant theorem to fix everything. Instead, they point to a fundamental flaw in the expected utility maximizer model, suggesting that it isn't as widely applicable as early AI safety researchers thought.
The failure of the agent foundations agenda has led me to believe that expected utility maximization is only a good approximation for mostly-unembedded systems, and that an accurate theoretical model of advanced AI behavior (if such a thing is possible) would require a fundamentally different, less dualistic set of concepts. Coherence theorems and decision-theoretic arguments still rely on the old, unembedded assumptions and therefore don't provide an accurate predictive model.
Philosophy is frequently (probably most of the time) done in order to signal group membership rather than as an attempt to accurately model the world. Just look at political philosophy or philosophy of religion. Most of the observations you note can be explained by philosophers operating at simulacrum level 3 instead of level 1.
In particular, if the sample efficiency of RL increases with large models, it might turn out that the optimal strategy for RLing early transformative models is to produce many fewer and much more expensive labels than people use when training current systems; I think people often neglect this possibility when thinking about the future of scalable oversight.
This paper found higher sample efficiency for larger reinforcement learning models (see Fig. 5 and section 5.5).
I picked the dotcom bust as an example precisely because it was temporary. The scenarios I'm asking about are ones in which a drop in investment occurs and timelines turn out to be longer than most people expect, but where TAI is still developed eventually. I asked my question because I wanted to know how people would adjust to timelines lengthening.
Then what do you mean by "forces beyond yourself?" In your original shortform it sounded to me like you meant a movement, an ideology, a religion, or a charismatic leader. Creative inspiration and ideas that you're excited about aren't from "beyond yourself" unless you believe in a supernatural explanation, so what does the term actually refer to? I would appreciate some concrete examples.
There are more than two options for how to choose a lifestyle. Just because the 2000s productivity books had an unrealistic model of motivation doesn't mean that you have to deceive yourself into believing in gods and souls and hand over control of your life to other people.
The reflective oracle model doesn't have all the properties I'm looking for -- it still has the problem of treating utility as the optimization target rather than as a functional component of an iterative behavior reinforcement process. It also treats the utilities of different world-states as known ahead of time, rather than as the result of a search process, and assumes that computation is cost-free. To get a fully embedded theory of motivation, I expect that you would need something fundamentally different from classical game theory. For example, it probably wouldn't use utility functions.
