It is really a pretty big question. My output on this blog has dropped off radically. Most of this is because the issues that I feel to be important have been written about by yours truly and I find rehashing the same old thing to be intellectually stale.
Most of the doomer literature fobbed off in blogs are TEOTWAWKI in nature. The world is ending. Life is going to be a pile of shit.
I think that the world is going to be just fine. The human race will adjust population-wise to a more sustainable level. The energy use of the smaller population will decrease in net and per-capita terms. A lot of the technological appurtenances that we hold so dear will be defaulted on. In other words, we will be living a life appropriate to our means, not our desires.
I beat a drum which no one likes the rhythm. The discordance of saying "we have taken too much, we cannot all be rich, we cannot all have everything"' is not appreciated in the vast majority. Hell, it really isn't appreciated by my fellow doomers.
I really can't see how the whole thing is going to play out. We might go Wiemar, or we might not, we might have a revolution, or we might not. A new Andy Jackson might rise and start things fresh, or he might just stay at home.
What I do know is that I feel strongly that change is coming. Unlike Harold Camping, I don't pretend that I have a secret formula where, if, I can just get my calculations straight, I can peer though a clear glass into the future. My glass is dark, and its reflections show much more of my prejudices and fear than the visions of a future world I so desperately wish to get a glimpse of.
