Comp is the theory that consciousness is the product of Turing-emulable processes, i.e. that it's a computation. Actually, that strictly does not follow. All that follows is that a computer can emulate certain physical processes upon which consciousness supervenes. This does not mean that consciousness is acomputation, in Platonia or anywhere else. I may have been too hasty. Comp ("comp1") is the theory that it's the /outcome/ of a computation, at some level. All that we know from the evidence is that consciousness superveneson physical brains. We don't actually know this, although the evidence appears to suggest it.
On that basis we don't ever know anything! That might well be the case, but science does not operate on such impossible certainties. We have a working hypothesis that consciousness supervenes on the physical brain. So far all the evidence supports this hypothesis, and there is no evidence to the contrary. That is good enough for the scientist in me.
