I believe in the cyclical rise/peak/collapse/rise/peak/collapse theory. The last couple centuries of Rome, to use a common example, were nearly, if not just as bleak as our current civilization, however our Kali-Yuga has been complicated by our technology.
I'm an optimist, as always the weak will fail and the strong will persevere, if not, than humanity will go extinct. It's a win-win. Obviously I prefer the former but its better than knowing my descendents will be living in this same type of shithole.
