alt Hacker NewsYou seem to be having a lot of difficult understanding this point: Literally the whole universe, including your brain that exists within it, is to our current knowledge a Turing computer. Am I talking to someone who actually doesn't know or didn't care to look up the computability power of a Turing machine?

A Turing machine is an abstract mathematical model that is not, as far as I know, physically realizable in the finite universe. A human brain cannot "be" a Turing machine.
"Behaves like" or "can be modeled by"? Possibly, although still not proven. But it cannot "be" one.
