I agree generally that people tend to assume the worst, but the reality is that since the 40's we now have the technology to actually end all life on earth in the form of nuclear weapons. We have never been closer to either outcome in all of human history. I am cynical in the sense that i believe human history will end in a fireball rather then a glorious space utopia. I don't see the middle path as a viable option.

Call me a cynic, but i find it hard to believe humanity will overcome it's social and political problems before we get to the Star Trek future we all want. I hope for it, but i don't think it's gonna happen.
