PG was a little ambiguous about this. He said "So I asked: What would I have said?" It is not clear whether he asked himself or ChatGPT.

The thing is, I have to trust that PG wrote the words saying he wrote his own response. What stops ChatGPT from saying those same words?

I'm wondering what ways/technologies we'll create to tell if someone actually generates text themselves. Right now, I can feel a rising desire to avoid text-based communication with people, almost a fear of getting catfished by text.
