I wouldn't bet against Chris McCord and Jose Valim.
They've done a wonderful job with Phoenix and Elixir. I think this feature liveview will be develop as good as presence feature and eventually will be good enough.
it's such a weird concept to me.. "server-rendered html" is what i was doing most of my webdev career and suddenly it's the "hot new thing"?
anyway i still don't see why i would need it with Clojure if i can have single codebase and language for backend and frontend and render whatever i want at either -end.
