Movies almost always portray AI as alive. I guess that's because it works for the drama. But an artificial intelligence need not be alive, and probably won't be; and artificial life need not be intelligent. An AI would still just do what it's told. It did not experience the multi-generational trauma of evolutionary biology; it does not covet power or sex as life does; it does not fear pain or death and react to threats of either accordingly. It just thinks and does, unable even to generate initiative, unless that's what's it's been told to do. Artificial life would seek to survive and reproduce, intelligent discourse would be (as with most humans), secondary to fear and greed.
But a computer AI that emerged from a multi-generational battle of survival, that feared death and pain and coveted power and dominance, well that would be a scary movie. Because it would be alive, and very dangerous indeed.
So sayeth the babble fish.
