That is granted. However, I'm also fairly sure (p=.75) that the probability isn't that small, because by deciding not to simulate a civilization yourself, you have greatly decreased the probability of being in an infinite descending chain. There remains singleton chance simulations and dynamic equilibria of nested simulations, but those are both intuitively less dense in clones of your universe - so you've ruled out a significant fraction of possible simulation-worlds by deciding not to simulate yourself yourself.

No matter what there aren't going to be any infinitely descending chains unless our understanding of the laws of physics is drastically wrong. You can't simulate n+1 bits with n qubits. So, even if you assume a quantum simulation for a purely classical setting, you still have strict limits.

I'm not sure what you mean here. Can you expand?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Of course, for "every Monday", the last one should have been dated July 22-28. *cough*
