There's currently no reason to assume that we're more than a complex biological computer - while it's indeed interesting to explain how subjective experience and qualia arise, it's certainly plausible that this can arise as emergent behavior once a specific type of computer is doing a specific type of computation, and we 'just' need to study that complex computation. Unless we obtain any evidence whatsoever that this can't be the case, Occam's razor would suggest that this is the hypothesis to explore, without looking for new physics or other unlikely assumptions.
