I have a theory (with no data to back it up; would be curious to get people's thoughts) that people with a religious or spiritual world-view, who believe that there is such thing as a soul, and that the mind is more than just a collection of neurons in the brain, are much less inclined to think that "AI" will ever reach a sort of singularity or true "human-like" intelligence. And likewise, those who are more atheist/agnostic, or inclined to believe that human consciousness is nothing more than the patterns of neurons firing in response to various stimuli, are more convinced that a human-like machine/programmed intelligence is not only possible, but inevitable given enough resources.

I could be wildly off base, but seeing many of the (often heated) arguments made about what AI is or isn't or should or could be, it makes me wonder.
