If it is gradual and emergent as you say, then where do you draw the line between an "unemerged" system without consciousness, and an "emerged" one with consciousness? Doesn't Occam's razor demand that we must assume the distinction is only of degree, and not of kind? If it were the latter distinction, you would have to have three theories -- one for unemerged, one for emerged, and one for the transition between the two. Having one theory (everything is at least infinitesimally conscious) seems much more appropriate given our current understanding of the science and philosophy of consciousness.
