> Emoji have never been effective or consistent at conveying meaning; at best they convey something to someone in the same subculture and time period

Isn't that the same with all words though? Think how much English usage changes in a generation. For instance, my girlfriend will use the term "I'm dead!" in a similar context to where I would say "LOL" and where my father would have said "What the fuck is loll?"

There's a spectrum. Subculture-specific slang changes quickly, but most words have a longer lifetime; reading Chaucer today is difficult but doable. Given that we don't encode words but only letters, for English you have to go back to the disappearance of þ to get a change that's relevant to text encoding. Emoji shift faster and are less effective at conveying meaning than any "real" language.
