I like playing with that space between laughter and discomfort where your discomfort can also make you laugh, and you're confused about the mixed feelings. That's challenging, and I think that's what makes for some of the best art.
If humans one day become extinct from a catastrophic collision, there would be no greater tragedy in the history of life in the universe. Not because we lacked the brain power to protect ourselves but because we lacked the foresight. The dominant species that replaces us in post-apocalyptic Earth just might wonder, as they gaze upon our mounted skeletons in their natural history museums, why large headed Homo sapiens fared no better than the proverbially peabrained dinosaurs.
