Singularity is a belief system, it has very little to do with AI.
edit: I also think if we would ever get to a point where AI gets close to a point of possibly getting out of control as you imply it would simply be banned in the US/Canada/EU/Australia. Furthermore Latin America and Africa could and would be pressured to go along if needed. Which leaves some parts of Asia. China, maybe India and Russia. Probably only China. It could be cut off from the Internet if needed. We could build up a wall just like in the Cold War. My point being: This will not happen just because it happens. It will be a choice.
