Anyone over the age of 25 actually developed their writing style before ChatGPT came about. Getting all uppity about these surface-level LLM ‘tropes’ is just stupid. I am thankfully yet to run into a situation where someone with this attitude is actually in a position to be able to negatively affect my life. I’m sure that there’s a correlation. Take the “ew, em-dash” stuff back to Twitter.
Yeah - writing styles have really changed over the years. Last time I ran a business document thru Grammarly, I was told it wasn't written at a 6(8?) grade level and was too complex :-P
When I first started out, I was taught you use passive voice in proposals (eg 'a program will be written..' not 'I will write a program...') since you didn't know who was actually going to write it. I can't imagine how that would go over now...
