Oh I think about these things a lot, just because I prefer a nihilistic, cynic (realistic) world-view does not mean I don't care about people, my surroundings, or anything in general, or that I go around telling people they are doomed and life is futile. On the contrary, I tell them to not worry too much and enjoy life as much as possible.

None of the above means I try to convince myself the future will only bring us peace and prosperity for everyone though...
