Turns out our brains are pretty good at math.

  There's no conclusive evidence that brains do backpropagation.

    Backprop is a different story but I believe brains kind of do dot products

      The math going on in the brain is very different to all this stuff. They're dynamical systems. Stochastic gradient descent is trivial compared to what the brain is doing. Plus, there are thousands of different types of neurons, with very distinct behaviors.
