I think The MasterNode/SuperNode, aka Privileged Nodes, aka Decentralized Distributed Block Creation, will replace PoW and PoS, both of which are young experiments in blockchain technology and are too messy to maintain in their current state.

Distributed processing, however, will not disappear any time soon -- the demand for processing power is increasing exponentially and the current supply is stagnant. Gridcoin definitely has a novel approach for securing the distributed processing market -- one that allows for the adoption of graphene and smart contracts and other protocols as they are created as opposed to assets which utilize centralized processing shares such as golem, iex, and sonm.
