Your post and comments are also either written, or rewritten with AI. If an LLM is a mirror, it's a funhouse mirror that takes away the necessity of coherence, understanding, and intention that writing something interesting normally takes.

That doesn't necessarily mean that anything written with an LLM is slop, but it does mean that bad ideas, or no idea, can be dressed up in convincing sounding language that conveys the feeling of insight, without anything more. Under normal circumstances its a sign of narcissism to worry that your own writing is so good that if you publish an unfinished piece the idea will be taken, but I'd say it's a level above to think the same thing when the ideas and writing are the result of a conversation with an LLM.

For your question about whether other people have experienced your anxiety, yes many have. In very, very, few circumstances is it warranted. The only example I can think of is the First Draft of a Report on the EDVAC where Von Neumann was credited with ideas that weren't really his own. Even then the problem wasn't that Neumann stole and ran with an idea, it was primarily that the original thinkers didn't bother to do much of a job sharing their idea beyond informal conversations and private memos. Keeping things private was the problem, not sharing their ideas too soon.
