40+ years ago Feynman worked with people building massively parallel hardware (not wildly different to a GPU) and got them applied to neural nets. Other than the steady improvements of silicon fitting more transistors on chips have we made any progress in CS at all? Or are we just applying layer after layer after layer of complexity on a bunch of already well known stuff?
