Many good things have been said. I would add that what give me comfort is that in the present moment, it is really, really hard to tell signal from noise. You often don't know the impact of people or events until many years out. We often said in grad school that you can't write history until at least 30 years have passed from the event. So, it seems chaotic and confusing because it is hard to for us to understand what it important and what is not.

The other thing is that every generation often sees the sky as falling in. An ancient Greek philosophy lamented about his parents had it all figured out and his children where going to ruin everything. That same sense of doom is pretty pervasive.

That is not to dismiss any of the real terrible things out there. Climate change is the big problem on the horizon. Nuclear waste is another. But I think on the balance, we are going to muddle through fine. The great blessing of humanity is that we are adaptable. The curse of humanity is that we are adaptable.
