Yes, there are these differences, but why should the differences be
relevant to the question of whether consciousness occurs or not? And
what about the case where the extra machinery that would allow the
right sort of causal structure but isn't actually used in a particular
situation is temporarily disengaged?
It seems to me that everyone contributing to these threads has an
intuition about consciousness, then works backwards from this:
"obviously, recordings aren't conscious; now what are the qualities
that recordings have which distinguish them from entities that are
conscious?". There's nothing intrinsically wrong with this method, but
it is possible to reach an impasse when the different parties have
different intuitions.
