People are often unconfident about their own writing. But if you can feed it to a LLM and have the LLM output something that looks coherent, your writing is good enough to publish.

Indeed, the LLM is not going to add (real) information; I'd say, publish both what you wrote and what the LLM spat, if you think someone would prefer the latter

If you publish the input instead, if other people feel it's not polished or whatever, they can run it through an LLM.

What OP did was destroy value instead of create it, you can always run it through another LLM with another prompt if you have the input, but you can't go backwards.

Just like we have a light/dark switch, we will have a Raw/AI'd switch.
