The point is "Claude is conscious" is a hypothesis with no explanatory gain, no empirical constraint, and by denying that non-human consciousness is relevant to the discussion it gains unlimited ad hoc flexibility. I am relating this to plausibility and causality because there is a much more rational causal explanation for Claude seeming conscious than it actually being conscious: it imitates human (modern Western) consciousness via big data. Since this is a totally different causal mechanism than human consciousness, and since Claude has nothing in common with non-human animals, and since we don't need consciousness to explain Claude's behavior, "Claude is conscious" is overwhelmingly less plausible than "Claude is a sophisticated but ultimately brainless chatbot."

It is truly irrational - and hostile to scientific thought - to believe Claude is conscious. It truly is believing in the Flying Spaghetti Monster.
