100% agree, at hackathons I start off by telling my team that the backend doesn't really matter we should just focus on a good interactive demo at the end (which is usually met with major eye-rolls). The only thing is that with Rails you can build the backend so fast and simply that it can be better to just use Rails if your team knows Rails. But my new thing is onboarding teammates who know React or Vue into Ember quickly then using Emberfire to build SPAs fast. Then we use cloud functions and firebase to take care of everything else.
