100% agree here. Way to many Rails developers around for it to die. Also as cool as Meteor is, and it's pretty cool. There is a huge continent of developers that will resist javascript for as long as possible, because even though it is ubiquitous, let's be honesty, it does suck in a number of ways. Ruby / Python / Go / etc.. are all so much nicer languages from a developer happiness perspective. Ultimately javascript will become more and more prevalent for sure, and Meteor along with it, but only because all the browsers decided to support it, NOT because of developer happiness.
