Yes, that is exactly the point I was making. That analogy was incorrect; the neural network is therefore likely to be not much better of an analogy to the human brain. At every point in history the favorite "model" of the human brain has been whatever the most advanced device we had made at the time. Just because that's now the neural network is no reason to think that we've found an adequate model.
