I homeschooled. We learned cursive (in fact some homeschool curriculum start with cursive, even before printing.)
My son’s cursive is atrocious now. He’s late twenties, has his Master’s, his career is moving forward, and he’a gotten regular promotions...even though his handwriting is awful and his signature is a scrawl (come to think of it...when I write a card, or note, I use a mishmash of cursive and printing...so my cursive isn’t so hot either.)
In today’s world, where does one use writing...except for cards, and checks (which are a dinosaur...only person I know who writes checks is my 89 year old dad:)
I understand the point of your post, but penmanship isn’t a necessary skill for success in life or in the workplace.
I totally understand your point having been in IT (VERY technical - manufacturing side) for 37 years.
However, it’s good for a developing brain. You know, that synapse thingy..
There will never, ever be another Newton, da vinci, Michelangelo, Brahms, Bach, nor Beethoven. (if you get my drift)
