PrinceScamp - I really don't understand why the world in 2109 will mostly be dealing with the same problems we're dealing with now, but then to the second degree. I'm pretty certain that the problems that will have to be tackled then will be, for a good part, different. Most of our worries now aren't the same we had in 1909.
I also have my doubts on a lot of those statements, because they're mostly based on a world caused by inaction. You can deride humanity for many things, but when it's our own lives and property that's at stake, we can be surprisingly cooperative and innovative.
And as for my personal view, well, I have no idea really. It'll probably be substantially different, in many ways. I can't say if we'll go more into the positive or the negative direction, that's for a good part for our generation and the ones coming to decide.
