Earlier quoted context omitted.
You cannot look up "beep" in the manual when you have 40 beeps. You are not objectively worse off with a word than a beep, even if you do not understand the word. Driving a car with beeps and chimes and dings means they all mush together and get ignored.
Feels like it'd be easier to differentiate jingles compared to different words of a language you don't know. You can vary intonations etc, but by that point you're back to jingles.
Maybe some people think R2D2 beeps and chirps are better, but sorry, I have no interest in learning the binary language of vaporators.
