Honest Trailer about Age of Ultron; it was really "roughly one week of Ultron". But we could, perhaps, say that we are in the Age of Ultron.
As he lectures the twins in an abandoned church, Ultron lists off things that demonstrate his thesis: that men create the thing they fear. "Men of peace create engines of war. Invaders create avengers." Men make monsters. They make weapons. They make.. children.
Is that what we fear? To Ultron it is. We fear children, because they will end us. They are made to supplant us, and they mark the end of "us". We've had children, and now that's it. We're done. Our lives are over.
Black Widow's trainers see children in much the same way. At their "graduation", the products of that training program are sterilized. Children are "the only thing" that might supersede the mission. She says, "it makes everything easier", and her face clearly shows the lie.
Ultron, like some of us, justifies his work with religion. Sometimes God "throws a stone", like the Biblical flood of the meteor that wiped out the dinosaurs. Ultron would destroy humanity for our own good. Some of us would as well -- ending races, eliminating children, sacrificing people "for the good of the planet". There are too many of us. Too many breeders and not enough earth to go around.
Of Stark, Scarlet Witch says, "Ultron can't tell the difference between saving the world and ending it. Where do you think he gets that?" Where does he get it? He gets it from us. From the selfishness of our culture. He gets it from the people that share Ultron's view, that people are the problem, that children are the problem.
Spreading across our real world is not Ultron's
mind but his mindset. Children are the enemy. Humanity is the enemy.
Life is the enemy. That is the age in which we live.
