I'm not sure why older folks act like writing in cursive is some sort of relevant superpower. I'm in my 30's, learned it, and never once used it.
"Whachu talkin' 'bout Willis?" Hell, I learned cursive in the 3rd grade (mid 60's) (Noble method as opposed to Palmer). And the degree and length of time to/with which we had to practice it made it seem a lot like it was a "relevant superpower." Granted, I rarely use it now as I don't hand write stuff anymore (not even personal letters... they'd not be able to read them), but I will say it did help me create my primary "signature" when I was like 12-13 (i.e. for signing documents, checks, etc. etc.). Of course, I made modifications to it.... it wasn't the straight letters from the Noble book, but it's based on that.
At one company I worked for, all the office staff was in the cursive generation and used it exclusively. And then they spent all of their time reading all their own notes to the person they wrote it to, because everyone's cursive eventually degrades into one fluid series of swoops that no one but the writer can maybe read. It was ridiculous and yet still somehow a point of pride for them.
"Eschew Obfuscation, eh?"
BTW, here's a video on some kids trying to learn cursive in 2021.
