>Imagine Erlang running in the Browser frontend and also on the Server backend. Everything would be uniform and clean and one would have a robust distributed system with all parameters taken care of by the "System" itself; [...]

That is a very compelling idea -- the idea of a language which supports concurrency natively -- such that a given source code base could be split up into "client" (web browser) and "server" (web server) components (and/or source code) easily, ideally automatically...

I think that is a very compelling idea, indeed!

This language might indeed be Erlang/OTP + Erlang(ERTS) + BEAM VM -- but it could conceivably be another language -- if that language was designed with the appropriate concurrency in mind: (https://en.wikipedia.org/wiki/List_of_concurrent_and_paralle...)

But that being said, Erlang/OTP+ERTS+BEAM VM -- definitely looks like it is worth further exploration!
