I think it is on those making the claim that a system equivalent to a Turing machine can have human level or superior intelligence. Humans are vastly more intelligent than any other organism we have encountered. I may be incredulous at the idea but the scale of difference between human intelligence and programs based on Turing machines is enormous.

The wholw point of turing machines is that they can emulate any computable system. You could have your a turing machine simulate every atom inside a human, and then you trivially have a turing machine that shows intelligence equivalent to a human.
