A problem with arguments by analogy...
Is that any analogy must differ from the situation to which it is analogous in some ways, or it would just be that situation. This problem is especially tricky when dealing with people in the grip of an ideology, because inevitably, what they will do is seize upon one of these differences, and play it up as if the fact there is some difference makes the analogy worthless. (Of course, if that were true, every analogy would be worthless, because, as I said, there is always some difference.) And so it went with my first round of Turing Test analogies . The point of the whole exercise was to show that black box tests don't tell you anything about where in a system the intelligence lies. If a computer passes the test, I would agree that is evidence that there is intelligence somewhere in the system! Furthermore, I can tell you just where that intelligence lies: it is with the programmers who built the program that enabled the machine to pass the test. Just like there is intelligence...
