Because it may feel slightly petty of me, but I don't want humanity to be going downhill. Most people on earth downloaded themselves/left for the stars, and the remaining folks decided that war, government, and all that bad stuff wasn't worth their time, so they just chill and let most of the world return to nature. Allows me to chill reading this without feeling a bit down. * Or they downloaded themselves into the robots. How's about that for ya?
