The article makes some oblique references to the stenography-like alphabet that Shaw had ordered to be designed after his death. You can practice it with an app (https://play.google.com/store/apps/details?id=net.blackenvel...) which accurately transcribes from English to phonetic representation, which is nifty and could be transposed to other languages. But ultimately: one can understand why it hasn't caught on. Is it really such a problem that our writing isn't very phonemic…? Every person/dialect would have their own person orthography.
