Over the last three weeks, arsonists ignited calamitous wildfires in California and Greece, and the U.S. government granted permission for a company called “Defense Distributed” to sell electronic blueprints over the internet that people can use to make 3D-printed, untraceable guns. While each of those developments is disconcerting on its own, together they point to something even more disturbing on the horizon–the advent of 3D-printed, untraceable, aerial attack drones.
This future weapon concept is simple (and for that reason, inevitable): Imagine a quadrotor Amazon package-carrying drone, but made entirely from 3D-printed components and generic circuit boards, assembled in a garage by following YouTube tutorial videos, carrying a small weapons payload like an incendiary bomb or nail bomb instead of an Amazon cardboard box, and loaded with better sensors and AI than we have today, allowing it to follow complex instructions and execute multi-step attack missions. Such a weapon could be made today with difficulty and at high cost, but could be made in about ten years easily and cheaply enough to put it within reach of terrorists and lone criminals. Thanks to better AI and sensors, the drones of the near future would be able to fly below radar, to take circuitous attack routes that avoided places were humans would see or hear them, and to drop their firebombs at night. One person with a nondescript van could drive around a large area (like all of northern California, or the eastern half of Greece), launch his drone every night on a carefully designed “bombing run,” recover it after a few hours, and then drive to a new location. Targets could be easily identified by looking at publicly available wildfire risk maps.
And if the drone failed to return, it would be of little consequence to the criminal who launched it because he could cheaply make a replacement, and because the lost drone would lack any identifying features that the police could use to trace its origins. The police would only find that the drone was based on a freely available internet file that millions of people had downloaded. Additionally, the criminal could program his drone to “commit suicide” during a mission if capture were imminent, maybe by flying into a nearby body of water or activating a simple self-destruct device. Any data in its computer chips would be destroyed, leaving nothing for computer forensicists.
These weaponized aerial drones could also drop small explosives instead of incendiaries, which they’d use to damage structures, vehicles or infrastructure, or to kill people at crowded events. Less dramatically, the drones could be used for vandalism and mischief, like dropping a brick onto the windshield of the neighborhood grouch’s car late at night. The military applications are obvious.
The barriers to making attack drones will only lower as time passes. Ten years from now, a malevolent person would still need to expend significant time and effort on such a project. Eventually, it might be as simple as vocalizing to your robot butler that you want him to build a drone. “Go use my Bitcoins to anonymously order whatever parts you need and then put the parts together.” It’s frightening to think about what might happen when anyone can commit destructive crimes remotely, and the financial and psychological costs of bad behavior get trivially low.
Frankly, I don’t see how homemade attack drones like these could be effectively banned. The relevant tech trends conspire to make the drones an inevitable development, and it won’t be long before they have super-empowered people who have terroristic or criminal intent. We’ll probably know when this dangerous new era has arrived when a drone is used in an attempted or successful assassination of an important person, like a world leader or member of the “1%.”
The only effective defense against small, weaponized drones would be a greatly expanded government surveillance apparatus (perhaps including its own fleet of drones for putting out wildfires or attacking bad guy drones), which is arguably a worse fate. Regardless, the threat will only be mitigated by more machines and more technology, which is in line with the broader trend for humans to become increasingly dependent upon technology for survival. At some point in the distant future, non-augmented humans like us will be outnumbered and will be the weak link in the chain.
