We need a theory of emergence to solve the binding problem, if it even is a problem. A complete theory of quantum gravity would likely still not tell us how consciousness works. So my point is, we do know this. We know exactly what is going on in an electric circuit, to the extent that we can rule out entirely that it is suffering. A brain in a vat that had always only been in a vat would feel no qualia. Real brains are fed a constant stream of sensation even before birth. I think a brain in a vat would simply die without stimulus.
