The more you use an LLM to write for you, the worse you will become at writing yourself. There is simply no other possible outcome. It's even true of spellcheck - the more you use a spellcheck the worse you become at spelling. I know this for a fact because I can no longer spell for shit. However, spelling is to writing as arithmetic is to mathematics. I also can't add up, but I have a degree in pure mathematics.
LLMs are a cancer on human thought and expression.
LLMs help to express what many people dont have the energy or ability to express. It also has a broader scoped view of protocol...It does not have emotions, which often leads to less than optimal discourse.
In many ways, it help those who are challenged in discourse to better express themselves...rather than keeping silent or being misunderstood.
This seems especially relevant for non-English-fluent commenters, who are increasingly using LLMs to be able to communicate more effectively on an English-only site like Hacker News than they'd otherwise be able to do.
It's still daunting posting in a second language, and LLMs are an attractive solution to that (depending on your definition of 'solution').
In any case, I don't think it's a bad thing to want to communicate as clearly as possible, and if an LLM helps you do that, I ain't one to judge. Sure, ideally I'd want to read folks' thoughts without the LLM-induced layer of vaseline smoothing them over, but even that's better than not reading them at all :)
Use them to get better, like how reading good writing directly (not summarized) will also make you a much better writer. Learn from the before and after so next time there isn't a need to reach for Ai.
