Going meta for a moment, this argument begs the question, assuming the conclusion "Therefore LLMs are not intelligent" in the premises "No intelligence can be ascribed to LLMs".

I'm not convinced it's even possible to come up with a principled, non-circular definition of intelligence (that is, not something like "intelligence is that trait displayed by humans when we...") that would include humans, include animals like crows and octopuses, include a hypothetical alien intelligence, but exclude LLMs.

I'm not arguing that LLMs are intelligent. I'm arguing that the debate is inherently unwinnable.
