But, the starting point of Neural Networks in the ML/AI sense, is cybernetics + Rosenblatt's perceptron, research done mathematicians (who became early computer scientists)

This is price in physics. Not price in Neural Networks. Starting point of Hopfield's and Hintons work in recurrent networks was physics analogy.

Their work does not advance the field of physics in any way, unless you insist to extend physics to each and every discipline out there.
