Composers were also handwriting masters. Bach also had incredible handwriting, there's a youtube channel about it.
I can imagine that in the time of Bach or Mozart that writing was a big point of emphasis in schools.
"Back in my day we taught the kids cursive!!" How many of them used fountain pens? I'm guessing zero. You just wasted their time instead of teaching them something valuable.
There’s your problem: guessing.
Knowing how to write cursive is a useful skill even if underutilised, heck, it’s a useful skill even if just for the artistry of it. It might be niche, it might be unnecessary, but saying it is a “waste of time” is just ridiculous.
No, it's not. At all
Please, let’s leave the made up arguments to the LLMs.
