At the end of "Age of Ultron", Vision said to the last Ultron: Human beings are very strange. I don't know why they think order and chaos are completely opposite, and they try to manipulate things beyond their control. But there is a grace to their failure, and you miss that.

Ultra replied: Humanity is destined to perish.

Vision said: Yes, but the beauty of things does not lie in their eternity.

(But a thing isn't beautiful because it lasts.)
