The thing is it makes handwriting go faster.
I was taught cursive writing. And I used to write volumes of notes and papers back in my school days. All by hand.
Thing is... I could write faster and more legibly by printing rather than cursive writing.
(I know, I didn’t practice cursive writing enough.)
Studies say that’s not really the case, people in practice on printing can go just as fast as people in practice in cursive. But even if they didn’t say that it doesn’t matter, nobody writes by hand anymore. The most I put pen to paper for anymore is shopping lists, never more than 20 items, usually abbreviated anyway. Even if cursive was twice as fast as print you’re talking about 2 seconds instead of 4. We are a typed society now, and printing looks closest to typed fonts, there’s no reason to learn anything else.
