Such an extrapolation doesn't make sense. You could also assume that all of New York would be speaking Italian by now given historical immigration rates. Foreign languages only tend to have staying power until the 2nd or 3rd generation. All these immigrants are going to public schools in their respective countries where the official language is spoken, it's expected that they speak it at their jobs etc.
