"The web has seen more transformations in terms of what is an "app" or a "website" in 8-10 years than ANY OTHER area in programming. It is only natural that widely different tasks need widely different tools to work with." These frameworks are not as different, though, so I don't that's the driving force. I think that the implicit argument of the article is that although new frameworks emerge, almost none of them get a large enough ecosystem or amount of adoption to become entrenched. The other thing that the author hints at is that there is a relationship between server-side platforms and choice of JS framework. Ember got a small lift because it was co-designed by one of the best and most well-known Rails developers, but Rails people seem to have gone to React, and Angular seems to have been adopted by the C# community to the point that Microsoft and Google run joint events. Thus newcomer JS frameworks are less likely to get enough adoption to stick around, because server-side frameworks now have implicit default JS frameworks.
