More questions:
1. If a purportedly intelligent machine had been built, how would you decide whether it was intelligent or not? I think that the Turing test is wholly inadequate for this task - see the well-known 'Chinese box' response to this test. (On a philosophical note, if an 'intelligent' machine showed signs of being intelligent, but you yourself could not really tell for sure whether it really was intelligent or not, would that really matter?)
2. Could an intelligent machine be created that could make moral judgements? Can moral judgements be made without emotion? Or can the process of making moral judgements actually be improved by removing emotion from the equation?
3. If an intelligent machine was created, that could see, hear, speak and move about, how do you think such a machine would behave? One nightmare scenario that some people may have would be intelligent machines marauding over the planet, replicating themselves and outwitting any human attempts to stop them, due to their superior intelligence. To quote the Time article: 'Introducing a superior life-form into your own biosphere is a basic Darwinian error.'
