Hah! I'm not sure about this. It could, but it also could help with language preservation.

I was quite surprised when GPT-4 was able to talk in Lojban to me. Somehow, I doubt it was intentionally trained to speak Lojban - that's a pretty niche conlang. So, I guess, it possibly picked some on its own, just from the books and dictionaries that were fed to it?

And to my amusement, it said that it doesn't speak Lojban, but can talk in the languages from my custom instructions... to my very limited understanding, all in mostly correct Lojban (except that it used "glico" ["English" in the sense of culture] instead of "glibau" ["English" in the sense of language]). Maybe it doesn't speak it well, but certainly does much better than I.
