The world’s major military powers have begun a race to wire AI into warfare. For the moment, that mostly means giving algorithms control over individual weapons or drone swarms. No one is inviting AI to formulate grand strategy, or join a meeting of the Joint Chiefs of Staff. But the same seductive logic that accelerated the nuclear arms race could, over a period of years, propel AI up the chain of command. How fast depends, in part, on how fast the technology advances, and it appears to be advancing quickly. How far depends on our foresight as humans, and on our ability to act with collective restraint.
AI offers an illusion of cool exactitude, especially in comparison to error-prone, potentially unstable humans. But today’s most advanced AIs are black boxes; we don’t entirely understand how they work. In complex, high-stakes adversarial situations, AI’s notions about what constitutes winning may be impenetrable, if not altogether alien. At the deepest, most important level, an AI may not understand what Ronald Reagan and Mikhail Gorbachev meant when they said, “A nuclear war cannot be won.”
