Utterly unrelated, but it’s fascinating how the word film has gone from “putting something on celluloid film” to “recording audiovisual data”, just like tar has gone from “tape archive” to “archive of file(s)” and car/cdr have gone from “address part of the register” and “decrement part of the register”, to first part of the cons pair and last part of the cons pair. As technology develops, words lose their meaning as mnemonics of technological underpinnings and become signifiers of the functionality of a technology.
