Sorry about that . I wanted to make a catchy title and had seen this meme around . <| sep |> Run down the pitch so it doesn ' t bounce <| sep |> Technologically , I don ' t think the bees would be viable . You ' ve got to put propulsion , computing , defensive , and sensory systems along with enough battery to sustain it in a package that small , and make it cheap enough to massproduce and cheap enough to deter theft . I would expect a realistic solution to be more like a quadcopter sized device with targeting power , perhaps . That said , you could easily recreate the story with some other fatal connected device . The expansion of Internet of Things in the home and computercontrolled infrastructure and bureaucracy in public could easily see a rash of , say , exploding batteries , hijacked cars , automated poisoning , offensive drones , liferuining data destruction or alteration , or any number of other attacks with just as much reach .
