At the pool I was talking to a guy who pilots a Very Expensive Plane for Big Institution. He told me about how his buddy planned his "fini flight" route with GPT, and then this guy I was talking to had followed the same flight route on an optional training. I pointed out to him that this means that an AI had directed the flights of Big Institution's Very Expensive Plane at least twice, & it seemed like it was dawning on him for the first time. He said it was his choice to have followed the AI.
