I wasn't familiar with Ambedkarism until you mentioned it a few times. Just from a little reading, I see that it combines a Buddhist critique of Hinduism and the caste system with a Marxist or socialist call for liberation from capitalist exploitation. I've written a number of articles that are critical of capitalism.
But I doubt capitalism will be deliberately reformed or abolished. What will likely happen is that capitalism will drive us into the ground and perhaps to extinction or else accidental technological developments will further decentralize power and free us from the plutocrats. It's a question of changing the environment to which we adapt.
Capitalism and neoliberalism are extremely powerful because they don't call for us to improve ourselves. We can be as selfish as we like and society is supposed to magically progress as a collective result of that selfishness, thanks to the miracle of the open market. Changing that system may require that we find an easy way to be less selfish, and technological self-empowerment rather than philosophy or religion will likely give us that chance, if anything will. Thus, capitalism may end up altering itself via its technological output.
