They are all "done" in that it is unlikely that anything will replace them any time soon. We don't event have, AFAICT, anything on the horizon. But there's a reason for that, and that is that the HTML/JS/CSS stack is the "virtual machine" or "assembly language" of UI development, and as such, we can't any more say they suck than does programming in assembly language. Assembly language is the "given" - unless you build your own CPU. This stack is likewise the "given" at the moment, and developers build an amazing array of tool, services, and billion dollar companies on this VM. Nobody controls this VM, so nobody can engage in rent-seeking behaviour. This has the pleasant effect also that most libraries built on top of are also open-source, and we end up with a very Darwinian landscape. We are now in the Cambrian Explosion, and the body plans that evolve must, by that way of thinking, be the best adapted for their environment.
