A bit of a basic analysis -- minds are brains and brains are just the go between some inputs and outputs, therefore they are just some sort of mapping, therefore Turing, therefore brains are computers. Conscience is the obvious problem to that analysis since there is no good reason that any sort of mechanism may give rise to self-awareness. Roger Penrose posits that's perhaps because it is a fundamental property of the Universe given expression by the arrangement of the brain. However, if that is the case the brain may not be "yet another substrate" for a mind -- it may be key -- and mind may not be a mapping between inputs and outputs -- it may be elementary. Another poster put it quite brilliantly: "perhaps creating a mind in software is like trying to create a magnet in software".
