It would be dangerous to teach anyone in ML what a function was, since they might realise, the premise of the entire activity is false. (ie., that in the vast majority of cases there are no empirical functions to model, no f: Pixel -> Animal) So better continue the current practice where few could distinguish a relation and a function; and fewer still are aware that they arent approximating empirical functions.
