I forgot to mention two things.
First, when it comes to the end of the world through our own destruction (and by that I mean human error - and that error could be anything, from overpopulation to developing AI that becomes self aware and freaks out on us), I think SF readers and writers will make it out alive the most. Why? Because those who can imagine the all-too-logical AI: "Humans destroy the planet, thus they must be destroyed themselves" or be able to realize the fact that we might totally ruin our planet (Al Gore does not count, I don't care what you say, that guy is an idiot. Did you hear his speech? The beginning of it made no sense for God's sake) are probably the ones that will see it coming the quickest. We'll look at the rest of the world and say "Fuck this" and move to places like Colorado or Wyoming and live where it's quiet and end up going back to hunting and stuff to survive. So yeah, when you watch movies of post-apocolypse type stuff, those survivors are genre readers and the people that got lucky.
Ok, not necessarily, but come on. When's the last time you read a SF book or even watched a movie and thought, "Oh crap. We're headed that way aren't we?" Some of the stuff that went down in The Fall of Hyperion didn't surprise me at all. Think of yourself as plugged into the Internet 24/7. I mean like, literally. A little wireless Intel Processor in your brain. And after centuries of this, people suddenly get cut off from it? Hell yeah there would be people that would go insane. Then there's 1984 but I'm not going to get into that quite yet. Waiting until I read enough of it to truly go on a tirade of some sort.
The second thing also has to do with (naturally) The Fall of Hyperion. Maybe it's a moot point, or not even really a point, but it made me smile...chuckle a little. Not in a happy way, but more of the ironic sort. As in, "Why does that not surprise me?" Here's the passage that did it, and by the way, for those of you who've never read the book (probably everyone reading this), this takes place at least 700 years into the future (probably more), so we're at the year 2694 or so, and the only means of world connection (ship travel excluded) has just been destroyed, thus cutting all worlds off from one another:
"On Qom-Riyadh a self-appointed fundamentalist Shiite ayatollah rode out of the desert, called a hundred thousand followers to him, and wiped out the Suni Home Rule goverment within hours. The new revolutionary goverment returned power to the mullahs and set back the clock two thousand years. The people rioted with joy."
I'll leave you to think about that yourself.
