My mom was a superb secondary school English literature teacher. She favored descriptive rather than prescriptive approaches to grammar and syntax, but I’ve always said that she never considered a sentence too long AS long as it maintained proper case, tense, and sequence of pronoun references. I worry that anything designed to replace ME and my idioms while “cleaning up” my prose will erase personality from written communications.
I also think that all the stuff related to single-use emoji design is really an attempt to make it so that users NEVER put down their devices, and that is really sad.
