You know why LLM text is full of emojis?

drumroll

Because people have been using a lot of emojis before LLMs in text already, and LLMs have been trained on those texts.

This whole "You have emojis in your text, it's LLM!"-trope got boring really fast. Amazing to see (and to think of the implications of) so many people apparently being in emoji-free social bubbles before this, though.
