So since cursive is no longer taught, then us old folks can attack at dawn! (Read this in cursive, please!)
Not entirely true that cursive is no longer being taught, as T-c should be able to confirm for her area.
Among other things, it may be that students with dyslexia may benefit from the hand-eye coordination that cursive writing employs.
That alone may not be sufficient reason to continue its use and instruction, but I would note that among the first things we teach children in school is to “try to stay within the lines”, and other rules which appear to be related to being able to draft messages to other human beings.
I think it would be cool to be able to “pass a note” to your friend that, even if intercepted, could not be deciphered. (A really clever teacher might use this ploy as a tool to interest children in retaining a lost art.)
