The progression of our hostilities toward our fellow man:
Stones and blunt instruments
Sharp sticks
Sharpened stones
Bows and arrows
Metal blades/ Armor
Gunpowder
Firearms
Explosives
Cannons
Aircraft/bombs
Nuclear explosives
Missiles
Smart bombs
Drones
Cyberwarfare
Think something will ever send us back to the dark ages where we start over?
Will our capacity to use technology to improve lives get us past our need to fight over resources?
Will the human race evolve in such a way that the need for material things is not overwhelming?
Ya never know.
