It's been in use far longer than LLMs. Thought I'm not exactly sure when it came into common use. I'm pretty sure I've heard the term on Nova decades ago.
(edit: this is books data)ngrams says first use in ~1889 in use for a few years, flatline until re-introduction in ~'66, surprisingly peaking in ~'83, and current sitting at roughly less than half of peak useage.
Though it appears to have gained popularity from 2017-2021, it dipped in '22 and that's as far as ngram goes.
Yea, for sure AI brought it into the mainstream. The terms existed for a long time, but the number of people actually involved in it are really low so it's not going to show up much on trends unless something big happens in the field.
