Um… I’m pretty sure the fact that the average American from the current/previous generation can’t write well enough to read it is a problem that needs to be fixed in the education system, not forgotten because typing is easier. People still have to physically write in this day and age, and we’d best make sure they can do it properly.
Don’t worry, it was an exaggeration. I’ve only not been able to read my own handwriting like twice in my life.
