It’s not circular.
LLMs cannot be fluent because fluency comes from an understanding of the language. An LLM is incapable of understanding so it is incapable of being fluent. It may be able to mimic it but that is a different thing.
(In my opinion)
You might agree with the conclusion, and the conclusion might even be correct, but the poster effectively argued ‘only humans can be fluent, and it’s not a human so it isn’t fluent’ and that is absolutely circular logic.
