It would seem to me that this shift towards remote weapons would favor the military, not insurgents in the event of civil strife.
Shrinking the weapon system usually results in physics limitations on range and speed - a 20-ton plane can carry enough fuel to go 2000 miles, but a 1 kg drone might have enough charge to go 2 miles. This favors the defender and prevents the use of these weapons for power-projection. Drone swarms are great for close air support, field defense, and urban warfare, but you can't do precision strikes across a continent (but you can defend against precision strikes, as long as your drones are accurate enough to intercept a missile). That fundamentally changes the balance of power toward smaller political entities.
The transistor is the only physical process that I know of that has improved at that pace. What makes you think drones can improve to that magnitude?
