I don’t know, isn’t ”AI” more a family of technologies like neural networks etc? Facial recognition using such tech is and was always AI, while adaptive cruise control using a single distance sensor and PID regulation is just normalcontrol” and not AI? I never heard about AI being used in plane autopilots, no matter how clever.
