I think the end of humanity will be much sooner. We are already starting to have crop failures due to the warming planet, and corporate greed is doing next to nothing to stop the escalation.
Personally, I'm glad I was born in my era. I got to see the USA when it was at its peak. Our products were the best in the world, even the German Chancellor drove a Cadillac. People left their keys in the ignition of their car, and didn't lock their doors. And most of all, anyone who had talent could make a living being a musician, playing 6 nights a week in singles bars.
Now we are in the decline of our empire, but I get to see and use all the new inventions the digital revolution gave us, and I'll probably expire before the decline of the US is great enough to make my life miserable.
I don't think the youth of today are as lucky.
