I agree, there are two consistent points of view with regards to conciousness IMO: either it is an emergent property of systems regardless of what they are made of, so there is no reasons machines couldnt be concious even if none now are; or that conciousness is a supernatural quantity that isnt a property of mater and energy that can be studied by science.

I dissagree with the later but it is far more consistent than people who claim to be materialist but insist there is something magicial about the matter in brains that can not be replicated by other forms of matter.
