Nobody feels it is too hard to learn. You just made that up.
That isnt the issue. The term obsolete fits perfectly.
Cursive is obsolete in the age of digital communication. Just a fact.
Why learn something that is obsolete?
Well, if that is going to be your argument, then why teach standard printing, reading from the pages of a book, or writing out mathemtic equations on paper? We could basicaly do all functions and communication on some device.
But one of the problems the world is facing right now it that far too much of how we communicate, conduct business, and are educated is all digital. There is no default back to basic learned skills and principals; people are effectively then left without any survival skill sets. It is like people who would end up freezing to death when lost in the wilderness because they don't know how to build a fire. What happens when the power goes out during a prolonged emergency? Can't charge a smart phone for days, what do people do then?
Should we all teach our kids to drive a horse and buggy as well as a car when they are in their teens?
I don't see many buggies around unless I am in Amish country. But I can tell you that just like knowing how to swim, how to build a fire and a shelter, my kids all know how to reasonably handle and ride a horse, even as we don't own horses. These are basic skill sets, like hunting, fishing, and riding a bike.
We are really in trouble when we rely so much on digital transactions. Not only due to cyber criminal threats, but to power loss. Writing is as important to our human history and our development as learning to build a fire. The human brain in children develops more efficiently by tactile motor skills combined with sight and hearing. When we were kids we learned to spell, and how to group like colors with wooden blocks, something you will say is obsolete because the same things can be done with digital devise. But what I am saying, is that in children not having the tactile physical attribute actually stunts the developing connections from brain, to nerves and to muscles. Learning to write in cursive, how to form shapes and lines correctly, was part of learning, and why it was mastered by the 4th grade, and only improved on with practice over time. Like learning to play a musical instrument. All of music today could be learned digitally, but there is something more to brain development learning how to properly form that note on string or other instrument.
Not teaching cursive has anything to do with it being obsolete. It is due to political pressure to give mainly Black urban students a much easier path in education because they are not able to compete against Asian and White students. So, today schools are trying to remove things which they feel only further puts many urban Black kids at a disadvantage, like removing math, or not demanding proper spelling and grammar to pass a course of elementary study. That is what this is about, that and wanting more time in class for other social indoctrination.
Maybe we need to go back to segregated schools, but not by race, by expectations for excellence. One side wants to spend class hours talking about how they are victims and how to protest in style, and the other side wants their kids to learn math and science. The Chinese must be laughing at us for giving up on cursive. A culture where writing is VERY complex, but they still teach Chinese letters even in the digital age.
