In what now seems like a previous life, I once had a job sorting produce by hand (mostly picking out stick/stems, and animal parts) from a conveyor belt zipping in front of me. Even back then CV machines existed for at least some produce, but the plant I was working at had not yet updated.

This kind of work required a dozen or more people standing along the (much slower) conveyor belt, each trying to grab what the previous worker missed. Even at minimum wage, that sort of labor isn't cheap. This is truly amazing technology.
