Nice article. I have tried storj at initial stage to rent my free disk space. There is a concept called Infinite Computing that means computation for users is virtually free and unlimited. Billions of decentralized compute or data-storage nodes can provide very lost cost computation or storage to users. The way decentralized economy is growing, it will provide customers the opportunity not only to have low cost services but also to earn by using these services. Evolution of free social media (Facebook) to more incentivized, income-generative one (steemit) is already here :)
