The alarmists have always been wrong about this one, but if you read Revelations correctly and ignore the hallucinogenic business of the end of time, you'll notice that in alluding to wars and rumors of wars, pestilence, famine, and intense interfamilial disrespect it is basically telling the reader to keep eyes peeled, because then as now those four things are raging. So the world is always about to end, which makes heartening sense anyway, since nobody knows if we're going to be enslaved by hyper-advanced space aliens or vaporized by a rogue solar flare or ninja quasar.
What could be worse than the end of the world? How about the sufferings, frustrations, and injustices of the world continuing to exist? That's a pretty rough deal, but I guess something is better than nothing, and let's face it: the world is definitely a happening place full of things. So there's nothing worse than the end of the world, since what the end of the world really means in its lazy modern usage is the end of humanity, the cessation of civilization as we know it. Few people use it to describe a cataclysm that destroys the earth. Doomsday is the last day of routine in which the adaptive abilities of all animals are tested, and because of natural tenacity, some life will probably escape it, get thrown into Titan or another watery moon and come back in a twisted form in a couple billion years.
There is only the anthropological doomsday, really, in the popular imagination. For many, perhaps rightfully so, there is nothing after our extinction. It's a purely hypothetical question not really worth thinking about. For some it is a most interesting topic. Lots of good literature about it, or inspired by its idea, and a good deal of nonfiction that asks the question. In a couple of years there will probably be a cross-discipline course offered about post-human topics and lots of people will take it and imagine it to be worthwhile... I'll probably enroll in it for kicks if I'm going to have the time. I want to know the secrets of the future, I want to call myself an expert and get on TV and give out a few useless answers to basic questions and make sure to tweet about the appearance.
It doesn't take an expert to realize that, statistically speaking, this very minute in which I am hastily writing is the end time for at least one hundred people across the world, having died at this point, and in the next minute it will happen again. It's the relativity of doom, a sort of morbid relativity that nobody can really stand to think about for any length of time, or even imagine. The end times roll on, and the alarmists keep selling the long con where we explode the world or destroy the universe, because we're definitely capable of that. There is a true and verifiable process of slow self-destruction in effect that gets ignored every time someone sells the story that we are all fifty years away from horrible hunger, violence, or pathogen-related deaths. Most likely we will slowly sink beneath the waves of genetic drift a couple thousand years after peaking, and some upstart group of rebellious aliens will stomp the lot of us into the dirt before making the same mistakes after translating and slowly accepting our extinct but futuristic hyper-metaculture. (Note to filmmakers and authors: portrayed obviously as some kind of cool and sneaky download scene like in Independence Day).
Anyway I am pretty certain a world-shaking even won't end my lifetime. I am more worried about my personal end-time which fate has set, hopefully in the future, but one can never rule out terrible and humorously dark luck, like getting shot by a cop due to hilarious misidentification, or falling in love with death disguised as a beautiful and warm paramour, or adopting a haunted dog, or getting a crippling affliction by smoking cigarettes, or choking on a delicious and highly expensive meal at the peak of your life after getting signed for a three-book multi-million dollar contract with a highly esteemed publisher. Drug overdose (can be funny), suicide (heheh), or vehicular manslaughter. Gun shit,. Death by bareknuckle brawling wild animals no smaller than one hundred pounds. Frozen on a supposedly 'tropical' vacation. Possession by depressed spirits. Inexplicable combustion. Hate crimed to death on a Friday night!
