If it did, then you’d still not get any relevant results, because again, those aren’t things. A list of extant languages would simply be a list of all languages throughout history that aren’t delineated as some kind of proto-language developed by early humans. Such specificity is not at all conveyed by the term “extant languages”. The search engine can’t reply, “under what circumstances are they extant? Are Klingon, C++, Heiroglyphs desired results? They’re extant!”

I would agree insofar as “live languages” should autocorrect to “living languages”, but it is getting pretty into the weeds linguistically
