Future? What future?

You can try and be optimistic that scientists will finally harness the glory of fusion power, but i doubt it will happen. The day the fossil fuels run out, human society will go to hell in a handbasket, and once that happens, the process will be irreversable. We'll be stuck with a pre-industrial society forever, with the broken remnants of our once 'great' society decaying all around us. We think we're so brilliant, but ultimately all that will be left of us is a thin layer of broken plastic and glass, in between the mud and shale.
