Imho things change in the same ways they always have.
I remember the violent riots in France in 2005. They were a sure sign of the wickedness of man, of the 'criticial times' we live in. Surely these riots would spread to neighboring countries and likely lead to civil war? Yet here we are, alive and kicking.
The USA has seen many, many big riots in the past. Some of these race 'riots' more appeared to be localized civil war.
The apparent rise of democratically elected leaders who try to make themselves into dictators is worrying, especially because it happens in the most powerful countries too. Otoh, it's the people of these countries that allow such leaders to be elected and stay in power.
Pandemics have swept earth many times. We've been able to eradicate or control many common diseases. The current pandemic shows how much we've progressed in combatting disease....but we're still mortal and will stay that way.
What I find most troubling are the yet unseen future effects of climate change and their impact on humanity.
With a (somewhat) visible enemy like covid19 most people and governements are able to take swift and decisive actions, even when the economy take very hard hits. With climate change we seem incapable of taking similar far-going measures, simply because we can't imagine what will happen in 10 years if we don't act now.
