I think the problem is not about updatelessness. It’s more like, what people want from decision theory is fundamentally unachievable, except in very simple situations (“single player extensive-form games” was my take). In more complex situations, game theory becomes such a fundamental roadblock that we’re better off accepting it; accepting that multiplayer won’t reduce to single player no matter how much we try.
I agree that the situation is less ”there is a theoretical problem which is solvable but our specification of Updatelessness is not solving” and more ”there is a fundamental obstacle in game-theoretic interactions (at least the way we model them)”.
Of course, even if this obstacle is “unavoidable in principle” (and no theoretical solution will get rid of it completely and for all situations), there are many pragmatic and realistic solutions (partly overfit to the situation we already know we are actually in) that can improve interactions. So much so as to conceivably even dissolve the problem into near-nothingness (although I’m not sure I’m that optimistic).
