One facet to the computational theory of consciousness that is worth considering is the experience of qualia may be latency-coupled, because the universe itself isn't scale invariant in terms of physical forces, etc. So it may be consistent to run a slow mind on rocks or a fast mind on transistors, but only the latter would be conscious due to the state transitions occuring quickly enough. (for example) This doesn't answer why it's the case, but this degree of freedom would allow for a description of reality where a large pile of rocks being flipped around cannot experience qualia, which would be very surprising if it wasn't the case.
