What makes you think modern hysteria about unprecedented times is overstated and things around the world will continue on as normal well into the distant future?

I think you're asking two different things here. You're asking if there's a lot of Hysteria about catastrophic times. Which of course there is, that's pretty common, throughout human history basically every couple Generations think they're in the end times.

However the other thing you're asking is if things will continue as normal. Which of course they won't. They never do. Things will just continue, in a new way.
