Why? Turing emulability of the physics that supervened on is surely irrelevant.
Unless it plays a role at some level, like you suggest by attributing a physical
activity to something which is not used in a branch, but might be used in another
branch, for physical reason. In that case, *such* physical acitvity is relevant, and has
to be taken into account in the artificial brain, as it will be in the UD.
Although we know that brain processes are approximately classical, they are not strictly
classical. So is it Russell's hypothesis that a strictly classical brain, as in Greg
Egan's "The Singleton", would obey the 323 principle, but that real brains don't?
