How close is the 'Dark Fate' predicted for humanity by the 'Terminator' saga?

"Terminator: Dark Fate," the sixth installment in the long-running science-fiction franchise, opens Friday and posits a world in which a self-aware computer builds an army of killer robots it then uses in an attempt to wipe humanity off the face of the Earth. It's the same vision that filmmaker James Cameron dreamed up for the first "Terminator" movie in 1984, well before the advent of autonomous drones and advanced machine learning made the premise seem a little less science fiction. In that 35-year span, a variety of technological advancements in AI and robotics have brought elements of "Terminator" closer to reality. Artificial intelligence experts are confident, however, that the kind of independent AI and humanoid robots of the movie franchise are still far off. But they also offer a warning: the developments that people have made in AI and military technology could create their own kind of "Judgement Day." "AI is a powerful technology, but it's a tool, not unlike a pencil," Oren Etzioni, CEO of the Allen Institute for Artificial Intelligence, told NBC News.
