Ah, Armageddons the one. I used to watch that all the time when I was 9 when our Mexican neighbor we got to fix our TV "accidentally" hooked us up with free HBO.
Humanity will most likely be in post-singularity (a period of time after exponential technological growth) by 2036, so an insignificant little meteorite would be nothing a directed-energy weapon or high yield explosive couldn't handle.
It's more fun to imagine high-tech scenarios for blowing up that worry! In this case, the meteorite.but, ricatwo, it's more fun to worry.
