In 8 years we can look forward to using this... Where will other languages be in that time???

Ahh committee decided standards.

We can already use quite a bit of ES5, and it's not so old. I'm sure the same will be true of ES6.

Also, you can compile from ES6 to ES5 or ES3 I would expect, plus there's also server-side tech like node.js.
