Yeah, I didn’t need to envision every movie supervillain mastermind’s plot to create havoc and terror. You seriously underestimate the resources needed to pull off such a thing and keep it secret even if it’s technically possible. Why make “10,000” little drones when you can make a half-dozen bigger RC plane types that can do an incredible amount of destruction? The point is to start terror, which requires far less than your elaborate plot and conditions like “facial recognition”. You went off the deep end of a Marvel movie plot to wipe out a city. We all know that just a couple well-placed hits is enough to send the country into a spiral.
