The really funny thing is that we are going to see more and more coins moving towards regular changes to their algorithm to keep ASICs out, and effectively surrender their decentralization. Taken to the logical conclusion, a supernode that is issuing algorithm changes is no different from a supernode that is signing blocks directly, just vastly more inefficient. Since you are already centralized, there is no reason to have miners at all. It becomes a ponzi scheme where the rewards are paid out randomly to participants.
