I love pondering outside life. It's ignorant to believe that we are alone in the universe.
If we don't destroy society soon our technology could get insane. Eventually space travel could be much more of a necessity (for resources and living areas for people) and our technology in that regard could skyrocket.
Maybe there are other races out there that are much more advanced than us, and would have nothing to gain from a relatively barbaric society like ours. So they leave us alone. But if we got advanced enough they would contact us. Probably conquer or enslave us but they'd contact us nonetheless. That would be so rad. By then I'd be an old man and hoping for an exciting way to die or just have something exciting happen anyways.
