I don't remember people ever writing cursive like what I was taught growing up. People just self-servingly turbo-scribble some chicken-scratch and call it a day. The kid who can't read our B-movie elvish script isn't the one with literacy issues.
We either write within the ballpark of standardization, or we don't. I think kids should be required to put in as much effort into learning cursive, as people put into actually writing cursive. Which is to say, absolutely none at all.
(Sorry to people who actually write legible, clean cursive. I wish I got to read your output in the wild.)
