I don't think it's stupid to believe that the brain is somehow beyond turing computable considering how easy it is to create a system exactly as capable as a turing machine. I also don't think that anything in philosophy can provide empirical evidence that the brain is categorically special as opposed to emergently special. The sum total of the epistemology I've studied boiled down to people saying "I think human consciousness / the brain works like this" with varying degrees of complexity.
