1. More Jews speak Hebrew than any other language. Among Orthodox Jews, that has been the case for a generation (at least), but is not true even among frei Jews (unless you use the Israeli definition of Jewish, i.e. anyone of Jewish descent within the last three generations who hasn’t converted to another religion).
2. Americans are increasingly become “online” rather than “printed word” oriented, so when the goyim go post-literate (i.e.skill in reading is for specialists only), Yinglish will start turning into a new language, just as Yiddish did 1000 years ago, with the caveat that there is no guarantee that frum Jews will stay in America (especially if the “blue” side gains strength as their anti-religion bigotry will force us to migrate).
