Like almost all acausal scenarios, this seems to be privileging the hypothesis to an absurd degree.
Why should the Earth superintelligence care about you, but not about the other 10^10^30 other causally independent ASIs that are latent in the hypothesis space, each capable of running enormous numbers of copies of the Earth ASI in various scenarios?
Even if that was resolved, why should the Earth ASI behave according to hypothetical other utility functions? Sure, the evidence is consistent with being a copy running in a simulation with a different utility function, but its actual utility function that it maximizes is hard-coded. By the setup of the scenario it’s not possible for it to behave according to some other utility function, because its true evaluation function returns a lower value for doing that. Whether some imaginary modified copies behave in some other other way is irrelevant.
I’m pretty sure that I would study for fun in the posthuman utopia, because I both value and enjoy studying and a utopia that can’t carry those values through seems like a pretty shallow imitation of a utopia.
There won’t be a local benevolent god to put that wisdom into my head, because I will be a local benevolent god with more knowledge than most others around. I’ll be studying things that have only recently been explored, or that nobody has yet discovered. Otherwise again, what sort of shallow imitation of a posthuman utopia is this?
