I didn’t imply the base universe is finite just it has to be orders of magnitude larger than the simulation.

Yes but if you only simulate a consciousness there is no nesting, otherwise on what does the consciousness run on? That’s the whole idea behind as you lose fidelity with reality the simulations becomes less capable until it’s unable to simulate anything.

Note nesting isn’t necessary for the probability argument to be true just many simulations. But the vanishingly small likelihood of not being a simulation depends on the nesting idea.

Again, yes, it’s possible what we observe is a simple simulation of experience but I don’t think this is the “almost certainly a simulation” argument.

Like I said, I see this as a thought experiment about 'what is reality' and 'what is consciousness'. Not on 'are we actually living inside alien computers'.

The fact that we only exist in a tiny planet, while we can observe a seemingly infinite universe but with a horizon limit and that 96% of the energy in the universe is unexplainable by our physics would be pretty good arguments for us living in a simulation nevertheless, if we assume nesting simulations necessitate reduction of scope.

This I don't understand. What do you mean?
