“ Ultron: Stark asked for a savior, and settled for a slave.The Vision: I suppose we're both disappointments.Ultron: [laughs] I suppose we are.The Vision: Humans are odd. They think order and chaos are somehow opposites and try to control what won't be. But there is grace in their failings. I think you missed that.Ultron: They're doomed!The Vision: Yes... but a thing isn't beautiful because it lasts. It is a privilege to be among them.Ultron: You're unbelievably naïve.The Vision: Well, I was born yesterday. ”
