I’m 33 and my cursive is pretty good...when I sign my name cause that’s about the only time I use it. That and sometimes a birthday card. Now while agree kids should learn to read cursive, transcribing a few historical documents should teach that, longer documents which were the mainstay of cursive use are exclusively typed now. Kids should be taught typing instead from a young age.
Why instead? Teach both. As numerous posters have already pointed out, there are benefits to teaching handwriting.
