This is the point that became clear to me after my last response. I
came to the conclusion that your "mind-producing activity" or
"potential for mind-producing activity" was really just another term
for the substrate, because in any realistic sense, it's some substrate
that must produce mental activity. In an abstract or hypothetical
sense, what you're saying is true: if you could just transfer the
thermodynamics of mental states directly from neurons to silicon (or
whatever), everything else *would* take care of itself. But you can't
do that -- at least not in any way that I can conceive of. Energy
transfers are coupled to transitions in matter states. Solving that
problem is probably harder than a Moravec transfer.
