Everybody knows wrong, I realize now as I double-check this. The exact word "robot" was actually coined even in Czech for the play that brought the word into English, but it's derived from "robota", which is not just work in general but drudgework specifically.
I have always assumed that tATu's song "robot, robot, robot" is about how life is just work, work, work, but no, actually it's about a person who loves a robot. TIL because I looked up a translation. I don't know Russian!
