Whats worse is that as time goes on and technology further advances, we only discover more imaginative and effective ways to kill ourselves. Kinetic rod bombardments from space, or even crashing meteors into the planet, or developing precision nano machines that could target specific nationalities or other genetic markers for killing, are all in our eventual future as a species. We are not far enough removed from our relatively recent hunter/gatherer tribal nature to handle these technological advances, I fear.
