I think we disagree on two points. First, I don't think the influence of RoR was as sweeping as you do. This is probably just a difference in perspective or preference. Second, regardless of that, I think the JS ecosystem is well-enough explored that the chances that some single new idea or platform is going to dramatically change everything doesn't seem very likely to me. For reasons I've mentioned in my top-level comment on this page, I think diversity of the JS ecosystem is going to be with us for a while.
