I think Scott Aaronson has written on the subject, and has proposed that if a theory of physics does allow computability beyond Turing, that in itself is evidence against the theory.
I would disagree, at least I wouldn’t give it much evidence against.
In some sense, this is me being annoyed at how much people think that the principle of normality/Egan’s law universally applies. This is a very clear failure case of the principle of normality, because conditional on hyper computers being buildable, then it doesn’t add up to normality, but to extremes.
It has been speculated that quantum physics might reopen the question by allowing some new ways of calculating things that are not possible in classical physics.
No, quantum physics does not allow you to make computers beyond Turing machines.
