5. Alan Turing (1950) Computer Scientist Proposed: Turing Test Turing Test –If an observer was sitting at a teletype and communicating by only typing and reading messages, and he/she could not tell the difference between a human and a computer on the other side of the teletype, then the computer should be considered intelligent.

6.

7. Chinese Room Argument – John Searle (1980) Assertion: Computers that are programmed to execute instructions will never be “ intelligent ” Assertion: Computers that are programmed to execute instructions will never be “ intelligent ” Room with two chutes (one in and one out) Room with two chutes (one in and one out) People, who want to translate Chinese to English, put the Chinese writings in one of the chutes and soon after, the English translation comes out the other chute. People, who want to translate Chinese to English, put the Chinese writings in one of the chutes and soon after, the English translation comes out the other chute.

8. Inside the room is a man with a detailed script (program). He uses the English rules written in the script to manipulate the Chinese characters. The script is so good that when a Chinese speaker sees the translation he thinks the room “ knows ” Chinese because the translations are flawless.
