It'll happen, when someone finds the right way to market it to the masses. That's always been the challenge for decentralised services and cryptocurrency, they're neat technology ideas with reasons for their hardcore fans to use them, but they lack obvious use cases for the general public, or at least said use cases haven't been communicated properly.

When someone figures out how to sell the general public on these ideas though (and the walled gardens end up stuck against an idea they can't replicate due to their structure), then these things will become huge.
