In post-RESTful world we will use HTTP to get our files, and then establish socket connection to talk to our services, clients, servers and middleware. And that's where we've got first generation of frameworks and solutions like GraphQL, Falcor, Firebase and alike.

What we need to actually profit in post-RESTful world is something simple and standardized. GraphQL - just a pinch not dumb enough. Firebase is tied to their database solution.

After all HTTP was invented for good old days when keeping a socket connection open was expensive and taxing on hardware. RESTful and later Hypermedia tried to leverage existing infrastructure, but we don't need it any longer. We can keep sockets open, we just need someone smart with some spare time to get us dumb pipes.
