An actual Chinese Room would be unimaginably vast - whole planets, solar systems, devoted to the knowledge we hold implicitly. To illustrate - imagine you give the room (in Chinese) the text of Lord of the Rings, and then ask it which member of the fellowship corresponds to the "Wise Old Man" archetype. Any reasonably smart human will give the answer, "Gandalf". But the room would need to (in Chinese) make systematic notes of the characters, their relationships, their actions, and then somehow integrate all this into a categorisation under the appropriate archetype. I'm actually agnostic as to the question of whether such a room could be built -- as I'm agnostic towards the possibility of AI -- but assuming the room would not be inconceivably complex masks the complexity of the ordinary workings of human consciousness. --- Essentially: consciousness does not exist. We only think it does because the thing we think with is wrong. But because we think with it, we can't tell the difference. So asking "who is experiencing the illusion" is begging the question. As for your essential point, I hold that words like "think", "experience", "illusion" all rest on the more fundamental concept of "consciousness".

What if the Chinese Room already exists, and we call it a brain? It's the most complex object we know of in the universe and it collects and processes input for decades. That's a pretty vast amount of stored information from which to produce an answer to your question. We wouldn't expect a 3-year-old to provide the correct answer, but we would expect a 30-year-old. This is a big hint that the brain does in fact collect and store information for later use. This would be analogous to filling in the books in the Chinese Room. If there hasn't been enough time for all the books to get filled in, we won't expect the room to give correct answers. In addition, if someone has never heard of Lord of the Rings, we would not expect to get a correct answer either. That page of that book in the Room would be blank. As for which concepts rest on which, we have to be careful, when discussing consciousness, not to mistake grammar for reality. There is no way in English to express the concept of an illusory "I" in the first person. That doesn't mean it is an impossible concept.

  Whether the mind is equivalent to the brain is an open question. If someone built an artificial mind, that would massively raise my belief in the possibility that the mind is purely physical. But I hold that this is vastly more difficult than assumed. My point with the Lord of the Rings was precisely that you give the books to a person who hasn't read them, and give them a few weeks to work through them. A Chinese Room would take vastly longer to "process" the book and it's "understanding" (represented symbolically) would take up vastly more room than the book itself. Even to understand simple word problems (to do with arranging blocks, for example), the algorithm used by the Room would have to explicitly encode our implicit knowledge of spatial relationships, and be able to apply this knowledge to arbitrary problems. To understand literature at a human level, the algorithm would have to encode standard knowledge of human psychology, society, physics, etc. In principle this could all be performed with a giant lookup table -- but such a table would be the size of several solar systems' worth of matter. So I don't hold that a Chinese Room is impossible in principle, but I do hold that building a practical AI would require great advances in the understanding of our own consciousness.
