The technology to kill hundreds of millions of people has existed for around 75 years now. This has been dealt with in the past through deterrence, and likely will be dealt with through deterrence in the future.
If you could make a nuke in your back yard and hide it in your pocket the world would look a lot different now. Digital technology is everywhere, going to be a whole lot harder to deter that.
You might be able to hide like a hundred drones in your backyard. Enough to kill a couple hundred people, maybe.
You cannot and will never be able to hide millions of drones in your backyard. That’s the relevant difference here. And that is not a mere quantitative difference, that is a qualitative difference that fundamentally changes the situation.
