Well, there are many possible avenues for significant change of that kind - in fact it seems more likely to me that we will see this emerge in some of the 'poorer' parts of the world as a result of their need to survive/thrive and the limited array of other options available to them due to the biases of the existing mainstream economic systems.

I don't know exactly how long you plan on sticking around on Earth, but I will remind you that change is the only constant :)
