Answer 25

the chinese room problem describes a situation where a person who does not understand chinese is sitting in a room and is given a manual on how to respond to all possible sequences of Chinese symbols. To the outside world, the person in the room seems to understand Chinese, but in fact they do not. By following the manual he is able to manipulate symbols and numerals just as a computer does; he produces appropriate strings of Chinese characters that fool those outside into thinking there is a Chinese speaker in the room. The same should be said about computers. Programming a digital computer may make it appear to understand a language but does not produce real understanding.
