> Many students are rewarded for using flowery language in school essays

Not to nitpick, but I actually had the opposite experience in uni. My prof docked me marks for my flowery language, and honestly, good for her, my lazy writing style honestly sucks (see how I used "honestly" twice in the same sentence, lol).

Not to take away from your post or anything, just realising I got lucky with my prof. I agree that LLMs produce way too much output when generating writing (and code too!)
