I agree that there is a high risk of project abandonment and it is frustrating that we haven't yet found a consensus around javascript frameworks. But, I would argue that Rails became dominant because it was so much better than the alternatives, we're in the messy part of the cycle where we're not sure what the next great/common/standard library or framework is going to be, but on a long enough timeline I'm confident that the best abstractions/communities/frameworks/libraries will be the most popular, because they allow developers to produce the best things quickly. We're a part of the immune system that helps us to converge to that reality.
