It can certainly be seen as a simple prisoner's dilemma, but it's not in some very important dimensions. (E.g. given the core tech the most likely outcomes are not AGI but developed carelessly nonetheless capable of causing all sorts of societal damage.) Unfortunately our bitwit overlords love short term self serving frameworks like this one so it's easy to imagine them embracing a "what has the future ever done for me" strategy...
Can you say more about what kind of model you see this as?
>the most likely outcomes are not AGI
So long as it's non-neglible, it doesn't change the rational strategy. Uncertainty about whether ASI is achievable only reduces the magnitudes of the expected values of the payoffs, not their relative order. Adding a "global misery" scenario does not change the fact that "extinction OR king of the world OR global misery" is strictly superior to "extinction OR global misery".
