I find it odd that a technique intended to make writing with a quill easier is still taught.
I mean, I did a bunch of calligraphy (homeschooled weirdo) when I was a kid, and when you've got a fountain pen with a nib, or a quill (yes, I played around with them) or a brush (if doing Chinese calligraphy, for example) keeping the writing implement on the surface without having to lift and re-load with ink is a big deal. Writing anything with a quill is almost impossible if you have too many starts and stops, so cursive is what you do.
But nobody does that anymore. With a pencil or a ballpoint pen, or anything else that controls the pigment/ink/etc flow well there's no advantage whatsoever. Signatures are on the verge of not being required *anywhere* - I bought a million dollar house last year and did pretty much all of it electronically with a default signature that had been generated by Docusign. I've been scrawling a big "X" on touchpads when a signature has been required for years as an inside joke with my wife about our relative education levels (she *finished* her PhD and always likes to remind me...)
As long as my kids can write legibly at all, I consider it good. Learning to type well, on the other hand, is mandatory in our house. I certainly wouldn't spend my own time learning or relearning cursive unless I was very bored. If you want to learn a neat way to write, do some crazy gothic calligraphy or something that's actually cool. At least you can use that at Halloween, maybe.
