The 'it's rude to show your ai(llm) output' is a reference to this: https://distantprovince.by/posts/its-rude-to-show-ai-output-...

What is "this" exactly? Is it a well-known author or website? Or otherwise a reference that one should be familiar with? It looks like a random blog to me... with an opinion declared as fact that's quite easy to refute.

”This” is also the novel Blindsight.
