A world in which machines governed by artificial intelligence (AI) systematically replace human beings in most business, industrial, and professional functions is horrifying to imagine.

After all, as prominent computer scientists have been warning us, AI-governed systems are prone to critical errors and inexplicable "hallucinations," resulting in potentially catastrophic outcomes.

But there's an even more dangerous scenario imaginable from the proliferation of super-intelligent machines: the possibility that those nonhuman entities could end up fighting one another, obliterating all human life in the process.

The notion that super-intelligent computers might run amok and slaughter humans has, of course, long been a staple of popular culture. In the prophetic 1983 film WarGames, a supercomputer known as WOPR (for War Operation Plan Response and, not surprisingly, pronounced "whopper") nearly provokes a catastrophic nuclear war between the United States and the Soviet Union before being disabled by a teenage hacker (played by Matthew Broderick).

The Terminator movie franchise, beginning with the original 1984 film, similarly envisioned a self-aware supercomputer called "Skynet" that, like WOPR, was designed to control U.S. nuclear weapons but chooses instead to wipe out humanity, viewing us as a threat to its existence.
