Which can, in all fairness, be a benefit of it. Because you might want to write something that people can’t immediately read - notes to yourself, notes in class, a passed note to someone else.

I’m not going to claim I’m happy about having “cursive for handwriting” drilled into me and being forced to learn it, but I do think it’s helpful to know for signatures or when it’s fancy writing time. There’s not really a benefit to not knowing about particular thing/skill… almost ever. It’s like the most low effort skill, and all muscle memory._{___}
