It's Not The Terminator. It's worse.
I carry a concealed handgun, legally. I’ve thought pretty carefully about what I’m willing to do with it and under what circumstances. Last week I realized it would be completely useless against a new threat I’m really worried about.
Let me back up.
I used to think the idea of a robot apocalypse was stupid. Not because AI isn’t potentially dangerous, but because the specific fantasy (Skynet wakes up, builds an army of chrome humanoids, declares war on humanity) skips about forty steps and gets basically everything wrong. Humanoid robots are hard to build, expensive to operate, and worse than humans at most of the things you’d actually want a weapon to do. The form factor is a liability.
I used to stop there. Dismiss the robot apocalypse, move on. I don’t anymore.
I’ve been playing a lot of ARC Raiders lately, which is a game where you are part of the last dregs of humanity slugging it out against (among other terrible things) autonomous flying drones. The developers had to nerf the drones to make the game playable. Give the AI realistic tactical behavior and semi-realistic physical capability and the honest answer is “this would be unwinnable.” So they tuned it down. Made the drones a little dumber, a little slower, a little less coordinated than they plausibly could be. And even nerfed, the drones are scary enough that they spontaneously caused human players to cooperate with each other. If you’ve spent any time in online multiplayer shooters, you know how remarkable that is. These games are not known for bringing out the best in people.
Real-world drone developers are working in the opposite direction.
I recognize how strange it is to be using a video game as a jumping-off point for threat analysis. But the thing is, I’m not actually speculating. Cheap autonomous drones are actively killing people in Ukraine right now. That conflict has become the world’s involuntary laboratory for exactly this technology, and the lessons are being absorbed by every military and non-state actor paying attention. The video game is fiction. Ukraine is not.
Here’s what a weaponized drone actually is: a flying landmine that goes looking for targets. It doesn’t need to navigate stairs or open doors or carry a rifle. It moves in three dimensions without caring about terrain. It can approach from any angle, including directly above whatever cover you’re hiding behind. It sees in infrared. It follows you into buildings. It doesn’t need to shoot you. It just needs to get close enough and detonate. The physical form factor isn’t a liability. It’s optimized for exactly this.
And here’s what one costs: not much. A decent FPV drone with a small explosive payload runs maybe $500-1000 fully built. A $200,000 home equity loan (the kind a moderately successful engineer could get on a Tuesday) buys you 200 to 400 of them. That’s not a thought experiment. That’s a shopping list.
But the cost isn’t even the scary part. The scary part is what happens when you have a lot of them at once. You’ve probably seen drone light shows at stadium events or big outdoor concerts. Hundreds of drones moving in precise coordinated patterns, forming shapes in the sky, no human pilot for each one. Just software telling the swarm where to go. That’s the technology. Now replace the lights with explosives and replace “form a shape” with “find a heat signature.” A single drone operated by a single person is scary. A coordinated autonomous swarm doesn’t need a pilot at all. It needs a target description and a launch command. After that it handles the rest. Traditional air defense systems are designed to stop a small number of fast expensive threats. Not 400 slow cheap ones arriving simultaneously from every direction.
I could build one in my garage. All the components are legal. I won’t, because I’m not a monster, but the reason I won’t is entirely ethics and not at all logistics. That is a very thin layer of protection to be relying on.
And you don’t even need rogue AI for this to go badly. You don’t need Skynet. You need one disgruntled engineer with a home equity loan and a Timothy McVeigh moment. The AI angle is almost beside the point. The tools are already here. The only thing standing between right now and a catastrophic autonomous drone attack on a civilian target is the moral character of everyone who knows how to build one. That’s it. That’s the whole security apparatus.
What doesn’t exist yet is any meaningful civilian defense against any of this.
A handgun is optimized for the threat model that drones bypass entirely. Wrong geometry, wrong speed, wrong approach vector. A shotgun is marginally better. Birdshot, wide choke, if you see it coming, in daylight, and there’s only one of them. Against a coordinated swarm at night you’re not bringing a knife to a gunfight. You’re bringing a gun to a drone fight. Same problem, different century.
There are some rudimentary civilian devices that do exist, technically. The net gun, for instance. Range of about 115 feet, can intercept a single medium-sized drone. Here’s the thing nobody mentions about that: you haven’t neutralized the threat. You’ve caught it. A kamikaze drone on a tether is now at chest height, closer to you than it was before, with you holding the other end. It’s like building a rat trap out of a bucket of water. Quite effective. Now instead of a rat problem you have an angry, wet rat problem.
The tools that actually work (RF jammers, directed energy weapons, laser systems) are federally restricted. A corporation can’t deploy them. You definitely can’t. The legal framework for civilian drone defense was written for the threat model of “annoying neighbor filming your backyard,” and it hasn’t been updated for anything else.
So there’s no civilian defense that can be realistically or legally deployed. What about civilian governments? Police forces? I’d love to believe they could effectively address this, I really do. These are also the same institutions that can’t reliably prevent a school shooting, which is one person with one gun. The idea that they’re going to develop and deploy effective infrastructure against coordinated autonomous drone swarms is, to put it kindly, a stretch. So that means relying on defense contractors, which has the potential to be so much worse.
The honest answer to “what actually stops a hostile drone swarm” is, probably, a defensive drone swarm. What’s a defensive drone swarm? Great question. It’s a thing my friend and I made up last week that does not currently exist, is barely even defined, and would require solving enormous engineering problems before it could. I also just watched Benn Jordan’s series on the security vulnerabilities in municipally deployed Flock cameras and robot dogs. Surveillance technology with genuinely terrible security holes, deployed by city governments that didn’t understand what they were buying. Now scale that institutional failure up to autonomous weapons systems. The same procurement process, the same IT department, the same gap between the people specifying the technology and the people accountable for what it does. Except instead of leaking license plate data, a security hole means someone else controls your city’s defensive drone swarm.
The doom loop is pretty tight. Individual defense is legally impossible to prepare in advance. Private deployment at scale requires political will that doesn’t exist. Government deployment at scale inherits the security failures we already see everywhere else. And the threat keeps getting cheaper and more accessible regardless.
When I try to explain any of this to people, I can see the moment they file it next to alien invasions. It sounds like that. Drone swarms attacking civilian targets in America sounds as plausible as a weather control weapon or a mind control satellite. I get it. I sound a little unhinged saying it out loud.
But the logic isn’t actually complicated. The technology is mature. The components are legal and cheap. The defensive infrastructure doesn’t exist. The regulatory framework is twenty years behind. And we know it works because we can watch it working, right now, in Ukraine.
I’m going to hate being right about this one.
