I think of the movie No Country for Old Men, and a scene near the end when Sheriff Bell visits Ellis, a wise old man confined to a wheelchair. With a worn and worried face, Bell tells his friend that he feels “overmatched” by the world. Ellis’s response is just as true about AI as it is about anything else that’s come down the road and frightened us with its awesome power: “You can’t stop what’s coming. It ain’t all waiting on you. That’s vanity.”
