To me, the really depressing thing is the way that JS development is becoming required of all web aps developers.  It is so dominant on the front end that you really can&#x27;t avoid it.<p>Even worse is the notion that because it&#x27;s already on the front end, why not write the whole thing in JS?  So now, javascript becomes the only language for the backend as well.  It&#x27;s not just Rails and Django that go away, it&#x27;s ruby and python.<p>I don&#x27;t think that&#x27;ll happen, like I said in a different comment, I do think that isomorphic ruby and other languages transpiled to javascript will play a big role in the resurgence of a lot of good languages that aren&#x27;t javascript.<p>Even if that&#x27;s not the mechanism, I am pretty much 100% sure that other languages will reassert themselves in time.
