You say that comp is useless, but what is your theory of mind. What is not Turing
emulable in the brain?
Its interaction with the universe.
Are you sure it is not the interaction with God?
Dunno, Samiya seems to the expert on what God does.
Can you explain why such interaction is not computable?
No, I was relying on your assertion that physics is not computable - which would entail
that brain processes are not computable, which would imply that comp1 is false. Except
there's a loophole: if comp1 means replacement by a physical object then the physics of
that object is not computable either and so it might work.
With comp, it cannot be computable, as the universe, if it exists, is not a computable
notion, a priori.
Of course that may be Turing emulable too, if the universe is. But in that case
you've just emulated everything, and emulated consciousness supervenes on emulated brains.
OK. (But then there is no problem).
There is a problem, because when everything is emulated "emulated" becomes meaningless and
you've only shown that consciousness supervenes on brains.
