The decline of writing is something that's been going on for a long time. Well written and grammatically correct emails are something that's been on the down turn. Consider how often people send emails in all lower case, lacking punctuation, or even without any sentence structure.

The "you need to write in a more professional business oriented way" is something that a lot of people are having difficulty with. Yes, this needs to be addressed earlier in someone's education more forcefully - but the SMSification of long form text started a while ago.

With that said, the "Ok, you need to write long form with correct grammar when sending an email that a director or VP is CC'ed on". It used to be Grammarly as the "install this and have it fix up your grammar and tone" ( https://web.archive.org/web/20191104093353/https://www.gramm... GPT-1 timeframe there). However, LLMs of today seem to be more accessible than Grammarly but it largely does the same thing - fix up and refine tone.

What I don't see from back then is people decrying Grammarly saying that it's making everything sound the same.

I'm also not sure if I would prefer the pre-fixup emails to what is produced by an LLM unless sending coworkers to remedial writing classes is something that is acceptable.
