I don't know enough to say what their odds are, other than very long. But one day, probably in my lifetime, we'll master fusion power, and it will begin a revolution that will make the industrial revolution look like a minor event. I don't think people realize that really cheap, clean energy solves pretty much every problem of scarcity. We'll enter an age of plenty like the world has never known. Limitless energy means limitless water, food, and materials. Of course it's not really limitless, but if it's even an order of magnitude cheaper than what we have now, the possibilities would be mind blowing.
