This is a very interesting video, but I have a bone to pick. More of a pet peeve. OK, it’s just me being a language fascist.
The word “chad” is its own plural. Or rather, the word means an indeterminate amount as opposed to a thing, meaning it can’t really be effectively pluralized, much like the word “paper” (in the sense of “Give me more paper”). Please, folks, if for some godforsaken reason you have occasion to talk about bits of paper clinging to the punch cards from which someone attempted to forcibly remove them, remember the term is “hanging chad,” not “chads.”
