Thanks for the insight! Still I have problems to identify "inteligence" in brutte force approaches, otherwise looks like a linear regression algorithm would lie also under the category of AI, and the original idea of AI, which the Wikipedia acknowledges included "reasoning" capabilities, I feel has not been yet incorporated/disentangled in current predictive algorithms. Whether it rises from things like that, I think we are not there yet and all seems to me not different from a linear regression algorithm, which I do not feel "intelligent" enough to place under AI. But I think everything is too vage also and there is a lot of overselling (including Deep Blue's "inteligence").
