All of this substitution stuff is predicated upon the possibility

convinced that it cannot based on all that I have studied of QM and
its implications.

This where the paradox of the philosophical zombie arises. It seems
pretty certain that a TM, given the right program, can exhibit
intelligence. So can we then deny that it is conscious based on
unobservable quantum entanglements (i.e. those that make its
computation classical)?

So is intelligence and consciousness, ala having 1p, qualia and all that
subjective experience stuff, the same thing in your mind?
Surely they must be related. If not, you do indeed get the p. zombie problem: someone who acts in all respects like a different person with (assumed) consciousness, indistinguishable in behavior, yet without consciousness. The question boils down to: let's say you knew some person well, they one day got a digital brain transplant, they still behave more or less as you remember them, do you think they are now without consciousness or merely that their consciousness is a bit changed due to different quantum entanglements?


Craig is making a good argument about this very issue. But I will not speak for him. My issue here is that it seems that you do not appreciate what is actually necessary to do a digital substitution. While whether or not the brain has quantum stuff going on can be put aside, the entire universe is quantum mechanical and not classical therefore any operation that we imagine doing has to be consistent with the strictures of QM or it is a fantasy. Classical teleportation is, like classical substitution, simply a pipe dream.
