I think a lot of people miss the point. If you're already an effective writer, obviously AI will usually only make things worse. But for people where English is not their first language (or whatever language you're writing in), polish is a godsend. It fixes your grammatical errors, vocabulary errors, spelling errors, punctuation errors, and all the rest. Obviously it can go overboard in changing your meaning (as any flesh-and-blood editor also might), and presumably over time these tools will get more refined. But for most people who write intelligent comments here on HN, you are not the target audience for this feature. Well, until you have to dust off your high-school French or Spanish or whatever for an e-mail exchange.
