I wonder if thereis a good explanation why emojis have had such an overproportional impact on LLM output. The em dashes I get, they are quite typical for formal writing, but I have never seen many examples of emoji-littered documents outside of LLM output or chatrooms before. Maybe I'm just out of touch with some corners of the Internet that this was trained on.
