did you see the disruption to air traffic? everyone that needed to land had to go into a holding pattern. the plane was communicating to tower and was going to land since it was emergency. it was not observing other traffic, part of landing is knowing the location of other aircrafts to avoid collision. This doesn't seem to have collision detection/avoidance and space coordination with other aircrafts and entering holding pattern to delay programming yet. This is a good start.
If they designed it to be used for every landing those issues would be resolved. The rarer you use features like this, the more disruptive they will be.
That's a really big if, especially since not all traffic has a transponder, and not all airports are towered.
It would need to understand how to visually look for traffic with a camera, and understand what intentions other pilots are communicating on the radio.
