I am convinced that we are going to go through some shit, but i'm not so convinced that it will be the end of the world. There has only ever been one true societal collapse in human history (Bronze Age Collapse. The Dark Ages was the fall of Europe only). There doesn't seem to be any indicator of a coming nuclear war.

But the economic system? Yeh, that's going to evolve quite a bit. We've reached a point that is historically repeated over and over again, where the game is stacked so much in favor of a small number of elites that the economy starts to slow down. And then the elite get thrown out the window and there is a massive surge and golden age within that society. We just have to hope that our rejuvenation doesn't turn violent like so many have in the past. 

Edit: Dammit you completely edited your post so now it looks like I am ranting.
