It seems like with the evolution of technology-- guns are ahead of it's time. So much energy is put in perfecting the perfect-weapon. Plasma is all around us, trying to confine this hot-mass, and put it into a firing-mechanism-- well, is a daunting-task. Bullets will someday be obsolete-- making way for the next-generation of assault-rifles. Killing an enemy can be done with 'fire-balls'-- instead of gunpowder. Humanity has been perfecting the gun ever since the Revolutionary-war-- and the 21st century is no different!
