I don't understand this view.
Do you think Dennett would predict that a person would instantly become unconscious if he were put into a complete sensory deprivation booth? It seems pretty obvious to me that he would continue to be conscious. There was a fad for sensory deprivation in the 1970s and from what I understand you sometimes would begin to hallucinate after a while, but you certainly still remained conscious (and I suspect the hallucination had much to do with expectations).
In any case, surely the Turing machine could include a modest VR simulation in addition to the brain simulation, sufficient to provide virtual environmental interaction. Or would Dennett claim that consciousness only occurs when the TM interacts with the "real world"? That would seem absurd.
