This is how I see how governance work with next iteration of system. I do believe it would be socialist from top and capitalist from bottom. System will regulate all economies to strike a balance between each other, but without compromising values which they inherently bring. Meaning communism, democracy, monarchy and autocracy coexist even with their difference. System is capable enough to bring best of every governing method. Not only that, choosing one over other will inherently kill a set of principles or erase cultures that people inherit from those differences. Essentially path chosen by each may vary but destination remains the same. If you could watch closer can see this, all small things adding up to a greater meaning or purpose.
All economies will be balanced from top, may be in simple terms I could say something like GDP per capita may be balanced across all countries. But citizens will get best of what they got from their ancestors. Also overtime geographies will evolve in such a way boundaries of all countries will fade. Concepts like global citizenship will take precedence. People across world can chose to live in any culture that they favour in liking without sacrificing their comforts of development. World will be a better place when each resident grows to their maximum potential and this happens only when they are welcomed to places where they feel like home.
