Tell that to 750,000 frum yidden and bnei Torah across the globe to whom Yiddish is the mama loshon, their native first-language, used for everyday speech. Many of whom aren’t even fluent in any other language. (They can sometimes “get by” with a botched English.) And the many more to whom Yiddish is their second language, that their Limud HaTorah is conducted in.
To them it isn’t 2012. It is 5772.
