But this just depends on how broad this set is. If it contains two brains, one thinking about the roman empire and one eating a sandwich, we’re stuck.
I suspect that if you do actually follow Aaronson (as linked by Davidmanheim) to extract a unique efficient calculation that interacts with the external world in a sensible way, that unique efficient externally-interacting calculation will end up corresponding to a consistent set of experiences, even if it could still correspond to simulations of different real-world phenomena.
But I also don’t think that consistent set of experiences necessarily has to be a single experience! It could be multiple experiences unaware of each other, for example.
