MikeAqua: Why do people assume that AI will turn nasty?
It's common theme in fiction because it makes for an interesting plot.
Most unethical human behaviour arises from some sort of greed i.e. an obsessive desire for wealth, sex or power.
If an AI doesn't have those desires, what is it's motive to go all SkyNet on us?
I read an opinion that intelligent machines may not turn nasty as such -- but, humans will be destroyed as a means to an end.
Such as how people will build a road without considering the life that will die or be displaced due to the road construction. We're not specifically trying to destroy the habitat, but it happens as a by-product of building the road.
AI machines may need to kill/displace humans to complete their projects - not out of malice but as a necessity to complete their projects.
Anyway,all science fiction at this stage. But, i wonder at which point you can consider a machine self-aware -- how do you know a robot is thinking and self aware as opposed to simply executing code.
