I wonder why people think posting undisclosed LLM writing is any better than posting some other person’s writing uncited. Even if the original author is okay with it, it’s still misleading and dishonest. Or maybe all these people would be fine having someone else write their content for them if it were free and easy? A social media is a reputation economy, but reputation doesn’t work if gaining karma requires no effort.

I think this is the cleanest formulation of why it's wrong that I've heard. It's simply plagiarism and misrepresentation.

It's because they view the LLM's output as "their thoughts." They told the LLM (via the prompt) what to do—often with loads of run-on sentences and long trains-of-thought. From their perspective, the LLM is just acting as a translation tool, saving them the trouble of having to think (about grammar, ideal wording, or even the order in which their thoughts should be presented).

They treat it as "just another tool" to improve efficiency. Like using a drill instead of a screwdriver.

Then there's people who are so lazy they give LLMs instructions like, "write a LinkedIn post about how AI is changing the future of work for thumbnail consultants." That's when it moves from "translating your thoughts" to "writing for you."

I think the issue is that it can be hard to tell the difference. We need better terms for these things so we can differentiate use cases.
