There's a certain point where this just feels like the Chinese room. And, yeah, it's hard to argue that a room can speak Chinese, or that the weird prediction rules that an LLM is built on can constitute intelligence, but that doesn't mean it can't be. Essentially boiled down, every brain we know of is just following weird rules that happen to produce intelligent results.
Obviously we're nowhere near that with models like this now, and it isn't something we have the ability to work directly toward with these tools, but I would still contend that intelligence is emergent, and arguing whether something "knows" the answer to a question is infinitely less valuable than asking whether it can produce the right answer when asked.
