Ember.js is a framework for writing web applications on the client side. This experience, and the end result will be a lot different that the type of web apps that you might be used to writing from the server-side.
I've created my share of Java-based server-side generated web applications, and when it comes to writing applications that run well on the web, JavaScript MVC frameworks are the way to go.
I can't comment on how it might affect your career on either the short of long term, though. That said, I expect that the demand for these types of rich webapps will become larger as we move forward.
I'm turned 22 ten years ago myself, but I think making that statement you made is unfair.
