I don't think GP was being snarky, how else would you expect someone to cite a name he recognized?
He was being snarky. He does actually end up citing who he thought the author was, and in doing so realized he was wrong.
He could have done that initially instead of saying "Google the name of the author."
It was not my best (nor normal) behavior, but the point in this case is that the OP offered very little in his rebuttal. A more contextualized reply would have improved mine as well. I believe actually the person that published this LLM course on GitHub works at ElevenLabs, as Google shows. So the reply could be: "Are you sure? I googled and apparently he works for ElevenLabs". That would have triggered a different reply. So I was not polite enough, and I said sorry, but given the exchange to say "google it" was not terrible, was exactly how I thought I had found it (I google for the wrong name, but citing MLX, plus X, and Google returned the wrong result). So it was a metter of "I did this way".
