Imitation Game
•
Turing wants to replace the question, “Can machines think?” with another
question. What is that other question?
•
What is his motivation for replacing his original question with his new
question?
Different Types of Evaluation
•
Evaluating Turing’s test for intelligence is one thing; evaluating the
claim “machines can think” is not the same thing
•
Even if there are problems with Turing’s test, it does not follow that
machines cannot think; if Turing’s test is good, that doesn’t prove that a
machine will ever pass it
•
First we will evaluate Turing’s test, and then we will examine the claims
that machines can or cannot think
Evaluation of the Turing Test
•
If a machine can think, then it can pass the Turing test. Is that true?
Is passing the Turing test necessary for a machine being able to think? Does
Turing think it is necessary?
•
If a machine can pass the Turing test, then it can think. Is that true?
Is passing the Turing test sufficient for a machine being able to think? Does
Turing think it is sufficient?
A
Few More Remarks on the
Turing Test
•
Why interpret the Turing (or Total Turing) Test as a sufficient test of
intelligence and not a necessary one?
•
How far have machines come in terms of passing either of these tests?
•
Some online bots… (don’t expect much)
Objections and Replies
•
Turing anticipates and replies to a variety of objections against the
idea that a machine can think. Today we’ll start looking at
–
the consciousness objection
–
the argument from various disabilities
–
the informality of human behaviour
–
the Lady Lovelace objection, which Turing interprets as
–
the learning objection
–
religious concerns
