I haven't written cursive in many years, i should try it again but since i'm out of practice i find it takes more time to write than going print. Which of course does lead to hand cramps etc
I would hazard a guess it falls below knowing Spanish but above folding origami cranes.
I have used it before when I've lost a phone etc, or if I had no way of contacting someone otherwise. I can think of more dramatic situations too. Technology can be helpful but if you're overreliant on it then that is a potential weakness.
