Sand storms so large they are blocking the sun in the US.
Radiation forest fires in Russia.
Ufo's existance were confirmed by US navy.
Stock market crash / rapid recovery
What's next...
The way it's written, it sounds like the US Navy confirmed the existence of aliens, but it was just unexplained phenomena, right?
I'd bet the most common ones are classified man-made objects. But yeah, nature throws some there as well.
UFO means Unidentified Flying Object. The word "unidentified" doesn't fit well with the word "confirmed".
US navy has seen flying objects which it has not identified. I would be more surprised if they could identify all the objects they have ever seen flying. I often have trouble identifying certain objects which aren't even flying!
During the dot-bomb implosion in 2000, most people threw their hands-up. Even VCs threw in the towel and moved from Calif. to southern states with no state income tax. (The metaphor was, "they're rolling up the sidewalks in Palo Alto.)
To this day, business people look at the start date of some of my projects and say things like, "Wow, you started a project in 2000?" Then they go mum since they realize what a silly thing that was to say.
Business and life are cyclical. Since it takes 7-10 years for a startup to mature, the passing of crises has very little effect in the early stages of a startup.
Now is the perfect time to do a startup or project.
Like a world-changing pandemic and riots? I'll be honest, it is getting hard to focus on building my cute little software bullshit project when a voice in the back of my head is telling me to spend my time prepping for social collapse.
