High-speed optical sorters are the sort of behind-the-scenes tech that make me feel like I'm living in the future. I have vivid memories as a child watching people winnow rice by hand using wide, flat bamboo baskets.

Had I seen something like the optical sorter back then, I would have thought it (Arthur C. Clarkeian) magic!
