I don't think the real issue is LLM posts. The issue with low quality on the Internet has always been quantity. The problem always has been humans who post too much, humans that use software to post too much, and now it's humans who use LLMs to post too much.
The problem with a medium that is completely free and unrestricted is that whomever posts the most sort of wins. I could post this opinion 30-40 times in this thread, using bots and alternative accounts, and completely move the discussion to be only this.
Someone using an LLM is craft a reply is not a problem on it's own. Using it craft a low-effort reply in 3 seconds just to get out is the problem.
If you had the LLM write the comment, then it wasn't your thoughts.
I sometimes wonder if people aren't forgetting why we're on this platform.
The goal is to have an interesting discourse and maybe grow as a human by broadening your horizon. The likelihood of that happening with llms talking for you is basically nil, hence... Why even go through the motion at that point? It's not like you get anything for upvotes on HN
Amusingly your comment carries some of the tropes of AI authorship ("is not a problem on it's own....is the problem") but it's not shaped like a profound insight is being discovered in every line is what makes it human.
How much of AI writing will pass under the radar when the big companies aren't all maximizing to generate the most engagement hacking content in a chatbot UI? Maybe it'll still stand out for being low quality, but I'm not sure. There's lots of low quality human authored content.
Not sure where my comment is going, I just kinda rambled.

No, someone using an LLM to craft a reply is a problem in its own. I want to hear what a human has to say, not a human filtered through a computer program. No grammar editing, nothing. Give me your actual writing or I'm not interested.
