DIRECTIONS: Read the passage and answer the questions that follow.

The contest between China and America, the world’s two superpowers, has many dimensions, from skirmishes over steel quotas to squabbles over student visas. One of the most alarming and least understood is the race towards artificial-intelligence-enabled warfare. Both countries are investing large sums in militarised artificial intelligence (ai), from autonomous robots to software that gives generals rapid tactical advice in the heat of battle. AI-enabled weapons may offer superhuman speed and precision. But they also have the ______ to upset the balance of power. In order to gain a military advantage, the temptation for armies will be to allow them not only to recommend decisions but also to give orders. That could have worrying consequences. Able to think faster than humans, an ai-enabled command system might cue up missile strikes on aircraft carriers and airbases at a pace that leaves no time for diplomacy and in ways that are not fully understood by its operators. On top of that, ai systems can be hacked, and tricked with manipulated data.

During the 20th century, the world eventually found a way to manage a pattern shift in military technology, the emergence of the nuclear bomb. A global disaster was avoided through a combination of three approaches: deterrence, arms control and safety measures. Many are looking to this template for ai. Unfortunately, it is only of limited use—and not just because the technology is new. Discouragement rested on the consensus that if nuclear bombs were used, they would pose catastrophic risks to both sides. But the threat posed by ai is less lurid and less clear. It might aid surprise attacks or confound them, and the death toll could range from none to millions. Likewise, cold-war arms-control rested on transparency, the ability to know with some confidence what the other side was up to. Unlike missile silos, the software cannot be spied on from satellites. And whereas warheads can be inspected by enemies without reducing their potency, showing the outside world an algorithm could compromise its effectiveness. The incentive may be for both sides to mislead the other. 

That leaves the last control—safety. Nuclear arsenals involve complex systems in which the risk of accidents is high. Protocols have been developed to ensure weapons cannot be used without authorization, such as fail-safe mechanisms that mean bombs do not detonate if they are dropped prematurely. More thinking is required on how analogous measures might apply to AI systems, particularly those entrusted with orchestrating military forces across a chaotic and foggy battlefield.
