The problem with that is that shorthand relies a lot on abbreviations: B = Be or By. But, at the end of a word, it can be ble, like tab. J can be J, or -age. A uses a single dot. So does -ing.
Because of that, I'm curious whether it would catch on or not.
I remember when they wanted to unify mobile phones and desktop computers, with a singular online storage account and DE that changed when you plugged your phone into a monitor. That shit was crazy.
