Iain Banks
Covered a lot of the issues of genuine AI - including AI with intelligence vastly beyond human - in his Culture novels. It is, perhaps, noteworthy that it is implicit in his treatment that the main means of enforcement of "morality" in his universe is peer pressure. In fact, one of his characters in "Player of Games" when tempted to do "wrong" notes that there are no effective dincentives EXCEPT that he would no longer be able to participate in society as he had before.
