My take is you should be skeptical but don't let that skepticism stop you from learning something new. I remember the complex UIs I and others wrote a decade ago with jQuery, now those aren't complex at all compared to what is common now. I feel that it isn't quite fair to say that back in the day we got along fine with just jQuery. Speaking of Backbone, I was already more or less organize my code like Backbone for a year when it came on the scene. Then there is the question, can I really program a custom framework better than an established framework?
