I always used to use the word "delve" a lot in my writings because, to me, it felt like a cool-sounding word that sounded professional, but I've recently stopped doing that because "delve" is considered a word AI loves to use a lot.
It turns out most AIs were trained by articles coming from a certain African country that uses the word "delve" more than it's used normally, and now, because of it, most AI-generated content has an unusually high amount of the word "delve".
