I worked in aviation in the late 1990s and automating ATC is all they could talk about. So, that's almost 30 years of talking and no action.

That's because it's a political problem, and not a technical problem. It could have been done then, and it can be done now.

Just curious: how many people in this thread know what SAGE was? A $5 Arduino has more computing power than the whole SAGE network. This isn't 1958, so we don't need the 'Semi' part of 'Semi-Automatic Ground Environment' anymore.
