...sooo what about super computers? If we can't agree on animals lets complicate the conversations even further. Can or will binary code generate emotion, free will and ultimately evil? Surely a super computer can be programmed (or even program itself) for self perpetuation, which is the primary responsibility of all carbon based life forms.
Since sense of humor is arguably the highest form of intellegence, maybe the question should be, do animals have a sense of humor? When I was having a few beers yesterday I swear my friend's dog smiled at me.
