I like using real idioms that have percolated through culture ('birds of a feather', 'white elephant', 'nip in the bud', etc), not stupid contrivations.
As someone who sweated through hours and hours of English essay-writing in school, LLM output that is misrepresented as genuine human writing is annoying and highly disrespectful of the reader's time and effort. The moment I saw the stupid, contrived headers and dozens of emojis, I closed the tab.
I refuse to waste my time reading the output of a matrix multiplication done in some server farm when I could do the latter myself.
