There is more to that, globalization. Now we have 8 billions humans. They are connected to the same infospace (internet) and share much more and more diverse content. Which means a lot more of emotional/interesting/helpful things. While each of them becomes less emotional.

Well, world changes dramatically. Connected old folks are like neanderthals in big city now. However not connected are still living locally in their minds. Youngsters are just accepting the world as it is. Nobody is amused by computers and cameras anymore. (at least in developed areas)

And with all that the worst is yet to come...
