    Real brains aren’t perceptrons. They don’t learn by back-propagation or by evaluating performance on a training set. They’re not mathematical models, or even mathematical functions in any reasonable sense. This is a “god of the gaps” scenario, wherein there are a lot of things we don’t understand about how real brains work, and people jump to fill in the gap with something they do understand (e.g. ML models).

      Brains are absolutely mathematical functions in a very reasonable sense, and anyone who says otherwise is a crazy person

      You think brains aren’t turing machines? Like, you really think that? Every physical process ever studied, all of them, are turing machines. Every one. Saying that brains aren’t turing machines is no different from saying that humans have souls. You’re positing the existence of extra-special magic outside the realm of science just to justify your belief that humans are too special for science to ever comprehend

      (By “is a turing machine” I mean that its behavior can be predicted to arbitrary accuracy by a turing machine, and so observing its behavior is mathematically equivalent to running a turing machine)
