In the eyes or should I say, lenses of the perfect AI Raum, this is a perfect world. Its objective is to serve their creators and make them happy, even if it do something like this.
AI Raum is perfect in the sense that it has no weakness, that means that it has no guilty conscience, no remorse, etc.
But those things are what it means to be a human, to be perfectly imperfect.
AI Raum maybe able to make a world with everyone's faces smiling, but like AI, its artificial.
