> I mean I don't want to spend time learning a framework that might be dead 2 years from now (remember prototype ?)

2 years ago I jumped ship from KnockoutJS to AngularJS. Backbone was also quite hyped out around the same time. All three of them are still around and frankly speaking it wouldn't have been a problem for me if the one I picked died by now. The skills I learned in Knockout helped me quickly learn Angular.

Think of it this way, learning on its own, regardless of what you're learning is valuable. My suggesstion, take a day and examine whatever frameworks you've heard of and pick one and learn it.
