Hollywood, mostly.

People also forget, or aren't aware, or simply don't consider the wide range of code structures than can be categorised as AI. The code controlling opponents in video and computer games; the assistants in smartphones, apps, SmarterChild, etc. are all valid AI and still a far leap from organic thought.

I think it's such a sticky topic because, even if we can't prove it's 'conscious' (which we also can't exhaustively prove it's not), something that can think form organic thoughts (i.e. not pre-programmed), that can believe it's 'alive' and assert as such, would be unprecedented. There would be people advocating for rights. There would be people insisting they're still just products. I don't think it'd be some messy breakdown of society like in fiction, but it'll be another tender nerve to stack along with all the other social issues humans have.

I personally agree with you and don't think we'll see true AI, at least not any time soon; maybe in some far-flung future with quantum computers, if we survive long enough without throwing ourselves back into the dark ages. Even so, the thought of a machine intelligence that can truly learn and adapt itself faster than we can blink definitely spooks me, though it'd only really be spooky if they had access to networked autonomous robots. Otherwise they're just a big scary monster trapped in a box which anyone can turn off.

But you also have to keep in mind that making slaves is exactly what some people would aim to do.
