This will be the reality until we come up with a way to make good decisions using direct democracy, and make that decision-making process so fast and easy that it can be used for any kind of group decision.

Concentration of power stems from our inability to make good decisions as a group of equals. We have to choose someone to make decisions for the group because there is currently no other working way to make them. Current technology might enable us to find some form of true democracy, but I'm not sure if anyone is looking for it.
