Well, the brain is not a back-prop NN, that's obvious. It's also obvious that a part of it is pre-wired for essential "life support", such as generating a heart

Well, the brain is not a back-prop NN, that's obvious. It's also obvious that a part of it is pre-wired for essential "life support", such as generating a heart beat, breathing, walking, sucking, etc. It's interesting to consider how deeply instinctive our knowledge of water is, but since our lives depend on it, I suppose quite deep, and thus related to that of other mammals.
