GPT can be useful for editing purposes, esp. for people writing in their second language or trying to find a more concise way of expressing themselves. (I'd often throw a phrase at GPT to see if it feels natural/idiomatic, instead of bothering my better half - an editor)
Having said that, if your goal was to make the responses here (on HN) more personalised, you achieved the opposite. Perhaps this is a sign of my personal paranoia, but I'm still not sure if I'm talking to a person or a bot. I don't mean to sound harsh, just thought it might be useful for you to know.
(FYI, I meant the responses here on HN. )
