Can be and has been. So, not compelling at all, I'd say. Even if you extend the general idea to a need to read grandma's recipes, you could post a pic online and someone who can read cursive could transcribe it for you.
I'm not arguing you have to be 100% self sufficient, but learning to read what amounts to a specific font shouldn't be too much to ask.
Spending time learning how to read a font optimized for hand writing that you might need to read a handful of times in your life seems like it would fall into the same category of work that’s not worth the time
Because of this, I learned to read them.
Because of this, I got slightly more out of the maps (and cover) of The Hobbit than most normal people — Tolkien used runes as merely a font for Dwarfish, which was really just English.
I wouldn't say that this is any more useful than cursive.
