The defeat of capitalism is a process of fits and starts and the subjugation (but not immediate elimination) of the bourgeoisie. That will take a very long time to complete.

Anti-capitalist revolution, though? I think we will see a lot of that if US influence continues to deteriorate, though it really depends on the exact approach taken by China et al ends up being towards smaller countries. For example, imagine if Chavez was elected in Venezuela in a few years and the US and UK were too tied up in knots to apply absolute pressure. Imagine they had 80% of their trade intact even if the US and UK applied as much economic pressure as they could. You can assume the SocDem/DemSoc project in Venezuela would be less disrupted, less in a siege mentality. But what would happen if the communists there built and defended lots of communes as separatists after a few years? Do China et al support the SocDems over the communists? They very well could in the name of stability. The new order may appear aesthetically much less radical even though the primary imperialists have been kneecapped.

Overall I am optimistic about overall developments. I think we will see a second and more lasting set of decolonization efforts, this time de-neocolonization and with more left involvement.

A big question mark is how the US reacts to the loss of its dominant position. I doubt that will go smoothly.
