What drives the popularity of a framework has very little to do with merit. RoR is still the right choice for lots of apps, and makes millions of dollars for lots of companies, no trendy frontend framework required. JS-heavy frontends and JVM microservices can end up being antipatterns from a user perspective. Increased engineering costs and decreased battety life are not strong selling points. When implemented poorly, SPAs and microservices are scarcely better than make-work for developers. Most of the time, you should just use Rails and be done with it.
