@hananc@llewelly@futurebird@SmudgeTheInsultCat I have heard it claimed that in China they say something like "it is the language of heaven". I don't know whether that's true (it seems a bit too much like the sort of thing someone not-Chinese might think the Chinese would say).
Relatedly, I wonder whether the graph is acyclic. That is, does it ever happen that country A regards country B's language as stereotypically incomprehensible, and country B thinks the same about country C, etc., until eventually we end up back with A again?
