I object to what mr "I know god personally and he is going to kick your ass" ritchie, says: no schoolgirl I know would like to be compared to thrash! Anyway, based on historical evidence your predictions might be correct if a virus or the like is involved, but you stated that intelligence is also an evolutionary factor. Although there are always localized exceptions I find it very hard to believe that the human race would knowingly totally wipe itself out. We are the first species that is aware of evolution and as such we are the first species intelligent enough to alter things to preserve ourselves. What you imply is that we have no self determination and therefore we might as well resort to anarchy until it happens. This would only speed up your suggested "implosion". I for one feel that efforts should be made to prevent conflict and educate and maybe we can guide evolution itself. If you are right you should lighten up more and make the most of what's left of your meaningless, insignificant life.
