James Cameron put it bluntly: “I warned you in 1984 and you didn’t listen”.

The director of Terminator isn’t talking about Hollywood nostalgia. He’s talking about Skynet, the military intelligence that, in his film, took control of the nuclear weapons and turned against humans. Cameron maintains that this script, written four decades ago, is no longer fiction.

His current concern is not that AI will write code or paint pictures. It’s that the world’s powers are already engaged in an artificial intelligence arms race: if democracies don’t build it, he warns, their adversaries will do so anyway, and escalation will be inevitable. His deepest fear mirrors his own film scene by scene: automated combat systems that act faster than a human can think, leaving no room to stop a conflict in time.

For Cameron, the line between his film and real technology no longer exists. If limits aren’t put in place now, he says, the result will be a system that no one will be able to turn off.
