> "understanding" the engine is required to advance it What I meant was more on the lines of "LeCun proposed Convolutional NN recognizing a promising paradigm", or "our prespective on Artificial Vision changed as we realized that the ANNs recognized textures instead of figures". > All computations And what I meant there was that in the chess systems of topic the calculations performed have been "as if symbolic", ie. reasoning on branches of consequences of the type "what could happen if I move this there" - even when adopting ANNs in some parts of the architecture -, as opposed to, say, "computing weights". That is the level "of machine code", not that "of electronics".
