What is a Machine? - not a person he does think that a human mind can be accurately characterized in the same way as a machine he is somewhat of a functionalist it is, if you are interested in whether machines can think, we want to know whether things like a laptop can think therefore, when we talk about machines, they are not humans, as we know humans can think and that would not lead to an interesting debate - a machine is an imaginable digital computer which is comprised by store: memory executive unit: central processor control: book of instructions, program What is thinking? - turing is cagey here, but he definately accepts the following... - using language in a way that is indistinguishable frmo an ordinary human speaker requores thinking - consequently, if something talks like us, it thinks - if this is the case, we get the imitation game - ex: someone is fishing, and “Fishing is only allowed on the East Bank”, green asks “Where is Joe?”, and purple said “the other bank” - secondly, you are at the Trust Us Savings and Loans, and the same exact conversation happens again - they have two completely different meanings - if you recorded yourself all day long and then looked back at what you said, it would not make sense outside the context - a computer would have to be realizing the relative context and this is unbelievably difficult for a computer to do - another ex: there is a soccer game and the coach says “It ʼ s purple this time” - in the first situation there is a purple and yellow shirt, and the yellow shirt is holding the purple ball, but in the second situation there is no purple ball - this is extremely complicated, yes it is easy for us - in these situations we wouldn ʼ t notice anything special going on and there are many phenomena similar to these The Imitation Game: Take One - there is a questioner and on the other side of a wall is two contestants; the questioners goal is to try to find out which contestant is male or female - questioner asks: are you female? - the man says “I am female”, as he is trying to trick the questioner - questioner asks: do you prefer pink or blue? they both answer pink - questioner then asks: are you lying? and the male eventually says, “I prefer blue” - if the male says: I totally prefer pink, he fools the questioner Key Idea:

- we think that when the male does this and fools the questioner, that you are intelligent and it was a good idea Imitation Game: Take Two - the same situation happens but there is a female and a machine - the machine is supposed to respond as a female human would - the same thing happens, but the computer says: I totally prefer pink - the questioner guesses that the computer is the female
