Keep in mind, none of these cautionary movies are based on real dangers. They're not talking about the difficulties in adapting the labor market to sudden improvements in automation, or the challenges of educating children who know computers better than you. Mainly because that film would be approximately as exciting as watching sloths fuck.
No, to drum up the fear, they've always had to invent a danger: "With a few keystrokes a team of hackers can blow up your house! Once computers get smart enough, they'll become sentient and start hating us! Robots will eventually cause the extinction of mankind!" And so on.
The whole idea is to play off people's ignorance on the subject. And people give them a lot to work with.
