I think ATC is overworked and there hasn't been as many advances in technology in that sector as well as under training for years. Honestly surprising that planes don't collide more often, the world around us relies on airplanes for logistics but everything about the entire aviation field from pilots to mechanics is a battle of never having enough people.

"quiet quitting" is just starting to be used as a substitute for "the lack of our workers ability to feed themselves and focus on their work is starting to impact job performance"
