I'm actually surprised it has taken this long.
What surprises me even more is that organized crime hasn't gotten on board much (yet). Like, screw drive by shootings -- drone dropped grenades on rival gangs and such.
Or that drones haven't been used for "school shooting" type mass casualty attacks.
Or that foreign countries haven't snuck in with a sea can full of drones which fan out and attack infrastructure.
Imagine a cruise missile as a drone carrier that just scatters anti-personnel drones along a flight path, each just finding a person indiscriminately.
If there's anything that Ukraine is teaching us, it's that we don't have countermeasures (yet). The autonomous versions are even scarier.
