We know how the room works--not the brain.

...Can we break it down and replicate it?

Can my sense of self be quantified?

What about animals, insects, viruses?

Is life unique, or an illusion too?

Or, are you the Chinese speaker, and the universe the room?

You seem to be arguing that because we can't do it yet, therefor it can't be done. Or that since we don't yet know how the brain works, that we can never know.
