There's also a glaring oversight in the motivational model for releasing a world-killer AI. While it's not impossible to imagine someone creating a genocidal AI for the sake of genocide, it's much easier to imagine someone doing it for ecological reasons, religious reasons, or nationalistic reasons. IE the person(s) doing it will have convinced themselves that they are doing it for the right reasons.
