In 1980, Searle presented the "Chinese room" argument, which purports to prove the falsity of strong AI. Assume you do not speak Chinese and imagine yourself in a room with two slits, a book, and some scratch paper. Someone slides you some Chinese characters through the first slit, you follow the instructions in the book, transcribing characters as instructed onto the scratch paper, and slide the resulting sheet out the second slit. To people on the outside world, it appears the room speaks Chinese—they slide Chinese statements in one slit and get valid responses in return—yet you do not understand a word of Chinese. This suggests, according to Searle, that no computer can ever understand Chinese or English, because, as the thought experiment suggests, being able to 'translate' Chinese into English does not entail 'understanding' either Chinese or English: all which the person in the thought experiment, and hence a computer, is able to do is to execute certain syntactic manipulations. Douglas Hofstadter and Daniel Dennett in their book "The Mind's I" attempt to criticize Searle's view of AI, particularly the Chinese room argument.
