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

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?

So is intelligence and consciousness, ala having 1p, qualia and all that

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.
