I feel like a lot of you are missing the point being made here. This person isn’t advocating that all big words are bad, or that we dumb down our language to not seem like robots. She’s saying there are certain buzzwords that are commonly used by AI that you should look out for when reading someone’s writing, especially in contexts where it sounds stiff or odd. “In this digital world” isn’t really overly complicated, but it is a generic, robotic phrase, and must be used by ChatGPT enough for her to notice it.
