Violence. The ability for a single individual to inflict mass casualties. However, I predict that gun violence will go the way of sword violence and bow/arrow violence, gun violence will become obsolete to a new predominant weapon...the drone. Consider drones today as what the internet was in its early years, just a thought of military application, but like the internet the future of drones will become a consumer product. As I write this I know it sounds almost Terminator cheesy, but the difference is humans will always be in control as opposed to being self-aware.
