Pffft. As a book editor, I can tell you AI is mostly garbage when it comes to real grammar. Grammarly is especially bad, suggesting errors in place of perfectly solid writing more often than not.
You've made so many great points, with the overall gist being that AI doesn't have the human touch. And we can spot the impersonal approach miles away: there's no creativity or quirk, but there are plenty of the most popular buzzwords that remind me of people trying to sound smarter by using the ten-dollar thesaurus word.
