Agreed, the virtue of a living language is change. I don’t always agree with the change but over time it makes language more expressive. A recent example is the word aesthetic used as a standalone adjective, as in “that’s so aesthetic.” While it strikes me as painfully meaningless — which aesthetic? — it’s common enough now to have been widely adopted as a general marketing term. That’s become an accepted use of the word, and so be it. I’d welcome the ability to more easily indicate tonal shift inside sentences, the way we do verbally. Just need it to become popularized enough.
