There you have it, the end of civilization.
It took thousands of years to perfect language and writing and only a single generation to get rid of it.
Technically writing is a form of drawing, it's hand-eye coordination, it's also art when done properly so if this is to become the norm we're about to have a new generation that not only won't know cursive, but probably won't know how to write, draw, etc.
The upside is that unless you're in 2nd life graffiti will probably cease to exist :)
