Nobody is writing sentences with autocomplete, much less entire comments. It corrects spelling, or at most homonyms or the like. Nobody is starting a sentence and pressing autocomplete to see where it goes.

And you should have to explain why you are using an LLM. Other people aren’t, and they’re doing just fine. You’ve said you think it helps in some way, but you can’t or won’t say why. That is odd to me. Do you not have confidence in your own ability to write?

Edit to add: As another commenter said, if someone wants an LLM’s answer, they can just ask an LLM. If you think you’re saving them that time and energy and asking the LLM and relaying the answer, then mark your comment as such (though IMO it’s still useless for you to post that). You having an LLM write a comment and passing it off as a human response is disingenuous at best.
