Or does this possibility really bother you?
Falls into the category of “Things I can’t control”. But I would stockpile ammo, food, water, etc.
Somehow I look forward to it. It means I don’t have to think about my career.
Not only that, but there would likely be ample opportunities to earn one’s way into Valhala. Assuming they let atheists in.
Hasn’t gotten me down so far.
My fury shall burn with the heat of a thousand suns if things fall apart before the Super Bowl.
I would be happy as a clam. Sure, I’d probably die of tuberculosis or get eaten by roving highwaymen but until then I could say “I told you so” to my heart’s content.
Well no. I love civilization and most of everything that goes with it!
I prefer to have civilization and stay a loner. That way I don’t have to do everything myself or die.
There is something very appealing to me about post-apocalyptic scenarios, and I think civilization is a little out-of-control now, so I do feel that I would welcome it in a way.
Think about it.
Without civilization, you have no:
Toilet paper
Medicines
Female sanitary supplies
Internet
Dunno about you, but I vote for keeping it.
Yeah, you’re right, the human race couldn’t survive without civilization. 
Hell no. There would be untold misery stemming from that collapse. I suppose there is a visceral thrill at having a genuinely high-stakes survival situation though, much like the idea of going to war.
I also like the idea of humans reaping what they sow, so that if generations down the road (if there are any) hear about us, they’ll be taught a scary lesson about hubris, etc.
I’ve yet to figure out how to make beer (and keep it cool) or whiskey, so I prefer that civilization-as-I-know-it stick around for at least forty more years.
You mean all civilization, including where I’m living now?
Or my feelings watching from afar as American civilization collapses? Dude, you’re asking me to start a blog or what?
Um, NO, why the hell would I?
Are you kidding? No civilization = no air conditioning. Also, I am fond of many other aspects of civilized life.
I would be happy in the same way I might be happy if I saw two trains mere seconds from impact. Sure, it would be awful, but I’d be a little glad that I was there to see it.
If it collapsed in a manner where all forms of commerce ended, but people weren’t murdering each other en masse, maybe I could be the John Steinbeck of that particular collapse, writing a few mundane novels about the times. Then, decades later when civilization builds itself back up again, perhaps based around the bartering of deep fried hog skin, students in 9th and 10th grade English classes will be forced to read my works and painstakingly fish out every metaphor or theme, only to slap them against the edge of the dock until its gooey insides have gone and all that remains is the beaten, useless hide of its original intent.
I would do my part to ease the downfall by constantly thinking of the children. Well, somebody has to do it.
