The worldwide air traffic control system is not simple or easy to understand and iterate on. And that's not because it was designed by idiots, or that you're so much smarter and more experienced and a vastly better programmer than the combined efforts of everyone in the world working on air traffic control, as you seem to be implying from your comfortable armchair.

Are you proposing the entire world simply give up air travel, because government regulations and industry standards and the laws of physics and chaos theory prevent you from having the simple easy to understand air traffic control system you envision?
