well, the problem is how far would you have to go? ok, you tell the AI to "not hack your opponent", what if they come up with a different cheating strategy? if you just say "don't cheat", what if they twist the meaning of cheating? it is extremely difficult to specify what you want so precisely that there is no room for AI to do something you didn't expect. and it is extremely hard to know if you indeed have managed to do so - without actually trying it on an AI. of course, current AIs are all just toys so they can't actually do much harm. but i hope you can see the potential danger here.
