A lot of the building blocks for mainstream use don't exist, but could conceivably emerge in time given Ethereum is Turing Complete. There are projects with a very high potential to provide those building blocks in development right now, like Matter Labs' use of zero-knowledge proofs to scale Ethereum: https://matterlabs.dev/ https://matterlabs.dev/ But yea it's all very speculative right now. I speculate it will work, but it'll depend on what the various players in the industy actually accomplish.
