He says the choice of Turing machine is unimportant to the overall measure but I am unsure of how the argument works so I can't explain it without trying to reread and understand that part of the paper. I think it is similar to how the choice of computer is irrelevant to the UDA or its exact programming implementation. > Usually such questions are answerable only in the limit n->oo; but is that > legitimate in deriving physical reality? > > I think physics is heading in that direction. Many of the roadblocks in various theories are hitting limits in understanding due to an apparent explosion of infinite possibilities. It happens in trying to go back before the big bang in inflation, in string theory when trying to determine the vacuum state we are in, in accounting for the fine-tuning of the universe, in trying to unify general relativity and QM, in explaining how quantum computers work. I think all of these lend a little credence to the idea that we are observers embedded within an infinite reality containing all possible observer states.
