Yes.
It’s just that airliners do not fly fully autonomous. They are under supervision by ATC, they fly in designated corridors at heights they do not choose for themselves at random. They are on flight plans and on schedules. Under normal conditions, where they start and where they land doesn’t change, and the airport’s ILS systems provide data for the on board systems. And they have at least two fully qualified and trained pilots on board.
I’m not saying that it’s impossible to scale that up by at least two orders of magnitude in terms of AVs in the air, buzzing around with a considerable amount of randomness, but it is not going to work with “just this one weird trick”. Time, money and lots of engineering still needed.
