Next few decades? I'm more worried about the next 10 years by itself. Imo we're looking at global economic collapse probably starting early 2027 or so. Then world war 3 probably by 2030. You could argue we're already in it. I just mean the big one (China vs USA). It may be delayed a bit due to the US just having horrible supply chains and needing time to ramp up production on bombs/missiles. I think they'll invade Cuba before Trumps term ends and use a bunch more too.

I'm expecting the Armenians to have some sort of civil conflict soon and the Ukraine and Iranian front to merge together for the most part. Israel will just continue to get more belligerent and expansionist. I really don't see how we could possibly avoid at the least a huge regional conflict at this point and the US seems hell bent on starting WW3 too.

The climate is going to suck, but people will adapt to it. China for sure. They're already working on all the tech they'd need to feed their entire country with hydroponics. Thorium for power will be the game changer. Generally the way of life most people in the west live now is just not going to last. It's unsustianable. They'll get a wake up call soon and will react by going full fash like the reactionaries they are. Then the rest of the world will have to reign them in. It'll be a mess and it'll happen faster than anyone would expect.
