I don't think businesses would be able to ever trust decentralized compute market. Where is the guarantee that the data/code that is sent to the network would not be intercepted and analyzed? It's much safer to sign a contract with a real organization, especially the one which has a reputation to uphold. If someone like DigitalOcean steals data from servers, they can be sued, and there will be penalties. If some decentralized miner somewhere does that? Nothing you can do. This only leaves decentralized compute to the applications where neither the data nor code does not matter. While I am sure there are applications like those (probably related to open-source or cryptocurrencies) I doubt they'll bring much money. (And don't say "homomorphic encryption" -- the overhead there is so high it is much cheaper to just get a centralized server)
