I don't think these nets are sophisticated enough to understand complexities of what humans call punishment / reward. Therefore punishment = -reward, but this is not the case for humans. If punishment for example is prison, is reward making people "even more free" for example giving them a flying car or something :-). If money is a reward (or punishment a fine), why are people not optimizing every last cent.
