Drones, Humans Greatest Weapons?

            The video implies that drones aren't the humans greatest weapons because even the chimpanzee's tool which is a "stick" can knock it down. It's funny how a chimpanzee defeated a human under the control of drones. What more if a human targets a drone using a weapon like missile? The missile will easily destroy it.  Drones still lack a feature to be considered as the greatest weapon.
