>The fallacy in the Chinese room argument in essence is that it incorrectly assumes that the rule-following machinery must be capable of understanding in order for the whole system to be capable of understanding.

No one can ever cares to explain this "understanding whole system" magic. You obviously cannot build a perfect sphere out of Lego, because there are no bricks with the needed rounded shapes. And likewise you cannot build "understanding" out of Lego, because there are no bricks with the needed "understanding" nature. Just saying "whole system" is no more an explanation than saying "magic".
