Retired ATC;
Almost 30 years ago, I attended a trade show where I was shown a crude mock-up of an "automated" ATC system. I smiled and went off to find a bar.
20 years ago, I was told by many people, including *pilots*, that computers would soon be able to do my job much better than humans. I giggled to myself.
15 years ago, the FAA wrote off a few billion $ in hardware and software that proved to be unsalvageable.
3 years ago, I retired. Last I looked, there were still AM com radios and radars at my old unit, and humans manning them.
Of course, 50 years ago, flying cars were just around the corner.
I ain't from Missouri, but they're still gonna have to show me.
