This is impressive. Use case is for an incapacitated pilot. It won’t work well or at all if the aircraft itself is having issues or in other emergency scenarios. As such it doesn’t replace the need for qualified pilots at the controls.
And I definitely see a future version that could handle engine failures. If you can count on auto land to flawlessly glide to the nearest airport, who needs a twin engine airplane? Single engine airplanes are significantly cheaper to operate than twins.
