The field demo I want to see, Human in the loop to failure switch over: Simulated failure of some form, where (for safety reasons) crew triggers ejection. This defaults the system to autonomous mode and the plane performs a safe landing.
If the pilot passes out during high-g maneuvers, the aircraft will pull up and bring the wings level until the pilot regains consciousness.
