Although obviously not possible to say definitively, probably on par with what it was before the enlightenment. The main catalyst for assimilation was not technological progress per se but was rather the emancipation which was solely an enlightenment idea. Modern scholarship has shown that before emancipation it was close to impossible for a Jew to be able to be integrated into the general population, I point you for instance to Endelmen, Leaving the Jewish Fold, Princeton University Press among others.
From your lack of criticism of anything I surmise that you concur with my previous post?
