I write bad, but my text editor is putting little grammar and spelling squiggly lines under everything and I click through them and end up with very AI-like text. My emails even end up with emdash in them. It’s to shrug. You don’t know if text today is completely prompted or is just cleaned up by modern grammar and spell checkers?

Sure I do. You're almost good enough, at pretending to lousy construction, to have fooled me. Use more words next time; the semiliterate invariably mistake volume for quality.
