In this scenario, Bob, who speaks only English, works in a room slid through a slot in the door, and it is Bob’s job to write responses. He does this by locating the written Chinese characters in one of the books. The book then tells him what to do; for example: If it is raining, draw this character. Bob writes the appropriate characters on the paper and slips it back through the slot. The Chinese speakers who wrote the questions and received answers are engaged in a conversation, but with whom? It’s clearly not Bob, who speaks no Chinese. And it seems silly to think that the room understands Chinese because rooms cannot be intelligent. Searle uses this example to draw a distinction between strong AI and weak AI. Strong AI is intelligence as we experience it internally, that is, having thoughts, feelings, and experiences. Weak AI is having a machine that is capable of doing the sorts of things we do with our intelligence, such as solving problems, making discoveries, interacting with the environment, and being strategic. was Marvin Minsky’s stochastic neural analog reinforcement computer (SNARC). Built in 1951, before digital computers existed, SNARC simulated the behavior of a rat in a maze. Amazingly, this computer could learn and, as a result, alter its search strategy; this weak sense. Scientists held two other developments as crucial to fully achieving weak AI. One was successful interaction with an external environment; this was instantiated in terms of the development of a self-driving car and was realized in 2005. The other element is strategic problem solving. Scientists believe that we will have achieved weak AI when a computer can outthink a person in a game of strategy, such as chess. 240
player having a king and a pawn and the other having only a king) can be thought of as straightforward logic puzzles. In 1912, the Spanish mathematician and engineer Leonardo Torres y Quevedo created an electromechanical robot that could solve such problems. In 1950, Claude Shannon extended the work to a machine that could play passably well in a variety of end-game scenarios. program to play a complete game. Bernstein, who was both a computer scientist and an accomplished chess player, said that the machine played a legitimate beginner’s game with the occasional remarkable move. To reach human expert level, it had quite a way to go. The invention of fuzzy logic by the Azerbaijani mathematician and speed of computer processors, led to the ability to create improved chess programs. Thus, in 1996, a team from IBM pitted their chess-playing computer, Deep Blue, against a grandmaster and former world champion, Garry Kasparov. Kasparov won the There is little doubt that weak AI—the ability to learn, strategize, and react to the environment—is well within our grasp. But the question of strong AI remains: Could computers ever become conscious, selfaware beings with their own minds? That is, can we create a nonorganic version of a functioning human brain? © LDProd/iStock/Thinkstock. 241
