Avi, this language has far more life to it among millions of Yidden, including nearly a million children who it is their first language, than you can ever imagine.
Yiddish is spoken by Charadim which is the fastest growing segment in the Jewish population so I tend to doubt it going to die anytime soon. It’s only dead in the Choloni community where only the old Russian immigrant who are dying out and some hard core socialist are the only ones speaking it.
