I wonder if we've actually been done as a civilisation since Chernobyl, and to a lesser extent the end of WW2 in the pacific - and are just a walking corpse at this point.
Makes you wonder where we might be now if the public at large, at least in western countries, had not become terrified of our most efficient energy source (nuclear)
Maybe the old 'go back in time and kill Hitler' meme should actually be, go back and stop Chernobyl.
