So I'd argue any algorithm that comes from control theory is not AI, those are just basic old dumb machines. You can't make planes without control theory, humans can't keep a plane steady without it, so Wrights Brothers adding this to their plane is why they succeeded making a flying machine.
So if autopilots are AI then the Wrights Brothers developed an AI to control their plane. I don't think anyone sees that as AI, not even at the time they did the first flight.
