Agree, but cursive is not the only writing style that's left to be forgotten into illegibility. Do you remember Fraktur typeface? You know, the writing commonly associated with the Third Reich. Needless to say, they aren't "Nazi letters" or even Gothic for that matter, but yet another writing style that had been in use for centuries, not only in Germany. Of course, it is true that the Nazis did greatly enjoy Fraktur, for being rooted in Northern traditions, and such things they were always suckers for.
What's more, Fraktur has its own cursive! So back in the day kids used to learn, read, and write all four scripts. But since the only benefit they offer is being able to read old texts, they are considered useless, and going rapidly out of style. The only exception I can think of are gang-tatoos or neo-nazi decos, which is quite sad, if you think about it. I know, I've always had a hard time reading Fraktur, though it's all just a matter of practice.
