Imagine it were 90% automated. Now imagine there's a 3 hour outage of the automated system.

You're left with a bunch of planes in the sky that can't stay there forever, and not enough humans on the ground to manually land them.

Now image the outage is also happening at all airports nearby, preventing planes from diverting.

How do you get the planes out of the sky? Not enough humans to do it manually.

Now imagine the system comes back online. Does it know how to handle a crisis scenario where you have dozens of planes overhead, each about to run out of fuel? Hopefully someone thought of that edge case.

This.

Remember when all the Waymos were confused by a power outage? Now do that, but with airplanes that will fall thousands of feet and kill hundreds instead of park in the middle of the street.

I'm not saying we shouldn't automate things. We should. But, it's not easy. If it was, we would have done it already.
