Practically all the ills we suffer currently are depressing manifestations of an aging society.

That, and the lack of real issues to solve.

Without thinking too hard I can name a few?

The rise of authoritarianism? Inequality? Revival of geopolitical "realism"? Decrease in empathy and holistic thinking? Increasing willingness of the general population to engage in political adventurism? Accelerating resource consumption (and decelerating resource stocks).

And if you consider none of those "real" problems, I know some people seem to have forgotten about it, but what about climate change? Given the half-life of CO2 and methane, that's a problem as "real" as they get.

If only we were all privileged enough to believe that the problems in the world today weren't real.
