Good. My 4th grade cursive writing was a waste of time. Studying anything else would have been more beneficial.

I think what they meant was "no matter how common something used to be, once we stopped teaching it in school it got lost quickly. Example: cursive."

Not "we should keep teaching cursive indefinitely."

I had to learn regular writing after cursive at the age of 20 eventually when I was forced because my instructors at the university would not let me use cursive. Those times were BAD.
