For humanity to survive we need a majority socialist world by 2100. With the fall of US hegemony and the rise of China the world will be much better for socialism to thrive. There will still be fascist holdouts in current imperialist nations for a while, but fascism is too unsustainable to win. If communism will win and not barbarism I expect to see a lot of progress in my lifetime (assuming I don’t get martyred or something). I think the scenario in Parable of the Sower is very realistic. We are the earthseed of this world. Capitalism will probably die in the next two centuries whether it’s in socialism or barbarism. Everything ends eventually.
Edit: my estimates are conservative btw, capitalism is deteriorating very rapidly and climate change is coming fast. However I am not sure what kind of role reactionaries on the right side of de-dollarization will have (India, Saudi Arabia…)
