IDK the models definitely do write qualitatively better prose (and better code) than the majority of people. If your definition of "human intelligence" is baseline performance of 0.2% of humanity it's certainly something else.
they don't, cite one example of well written LLM prose? they can definitely infer a lot more slop than people have patience to, and anyone writing or reading slop prose has realised this and replaced sitting around writing and reading slop wiith llm's writing and reading slop and then grug-brains paste 10k words of slop say "grok, pls summarize, no mistakes" and grok tells them "What a brilliantly written article! ...

Better code and better prose are not great indicators of intelligence. Can it help you survive in the middle of the jungle? Can it grow rice? Can it give you first aid?
