Airplane autopilots require human intervention only in rare emergency scenarios That is not even remotely true. Pilots must babysit the autopilot and do. When flying on autopilot you still constantly check instruments to make sure that the plane is going where it should, how it should, as fast as it should. They sometimes have faults, and they have caused crashes. Pilot training is VERY clear that AP can never be relied on. Eg: If you tell your AP to climb at 2000 ft/min, many will happily stall you trying to maintain that climb well above where your engine(s) provide(s) enough power to do so; if you tell your AP to descend to 3000 ft over sea level, most will happily fly you into a mountain that is in your way and rises to 4000 feet above sea level (in a better-equipped plane, TAWS will beep at you to tell you about this, but most APs will press on); if you tell your AP to maintain altitude, many will happily overspeed the aircraft in a large updraft, nosing down to avoid the climb.
