Javascript is eating the world because so much stuff runs through the browser these days and javascript is a given to be available. That alone will effectively stop the world from migrating away from JS. More and more people will give NodeJS a whirl, confident at very least that JS isn't going anywhere for quite a long time. It just creates a cycle where you're going to see very little slippage in JS usage and most of the time ever increasing usage. It won't be this way "forever" but we're probably a decade away from peak JS.
