alt Hacker NewsI would say if all of your doomastrophizing comes to light (the myriad of collapses and depressions and winters in your post), then there is no opportunity for anyone anywhere, and we should all stock up on bullets and cigarettes while we can.
But something tells me you won't do that.
Yup, absolutely! People before us already lived through the Great Depression, people already lived through two World Wars, and despite all that there were still some technological advancements made and some good opportunities amongst the chaos! There's obviously going to be pains from transitioning into a new world order, but humanity will still keep on living. Just don't expect the next world to be the same as before!
I think it's important to know and practice your passion, even if you have to work on something different to pay the bills. You can only be good at something if you really like it, and you never know what opportunity you'll stumble onto if you're ready for it.
