It will be relevant until somebody does a monolithic Web application framework that is better in a way that it so compelling that it's obvious. A microservices architecture is not always the right choice. Django, Laravel and other established frameworks can be a bit better or a bit worse, depending on your criteria. Buffalo (Go) and Phoenix (Elixir) are the only competitors that I know of that could match Rails at it's own game, and also have compelling advantages over it. Both have smaller ecosystems right now.
