The thing is some of these tools have enduring 100s of years. Multiple generations. Others have changed in just a single generation to be nearly unrecognizable (ipod -> iphone)and their existence can be wiped away by trend/market making/capitalism. Learning how to use a screwdriver helps even when the electric is out, the internet is offline, etc. etc. Learning cursive may not be as immediately helpful but we have all come to accept that developing more neural pathways is important and "smooth brain" is bad
