I think it's important to rethink this progression a bit. In the early years of Rails, what else was around? What other Ruby-oriented frameworks did we find that did what Rails did? How many people were developing web-based MVC apps on a day-to-day basis in comparison to how many are developing them now? GitHub wasn't even around until three years after Rails v1 - seems like maybe GitHub on its own will have untold effects on speeding up development time on a project like Ember.

Let's consider also the simple fact that ALL client-side MVC frameworks are JavaScript (unless they are precompiler-based, which none of the big ones really are, currently). The fact that all of them are based on the same language, the massive cracks in server-side systems that are further exacerbated by language idiosyncrasies are reduced significantly.
