Ironically, I think that's part of the reason it became trendy to hate on Ruby and Rails: they make it really easy to do things, which means they also make it really easy to do ill-advised things. But that's not really the fault of the lanaguage or the framework - writing good and maintainable code is a skill you need to work at and develop over time, no matter what language you're using.

Ruby is a beautiful language - Rails is opinionated (much like its creator). If the ways Rails is opinionated works well with your use-case, it's wonderful to use but if not, it's simply horrible.

I don't think RoR usage has declined (maybe as evidenced by the number of "I'm a newb" comments here?) but rather think it's become mainstream so it's simply missing the hype it had when it was the new hipster technology.

It's not so different to the same kind of elitism that gives, say, PHP or JS a bad rap.

They just happen to be successful, and popular.

I don't think the trope of Ruby being old and boring is such a bad thing either, it just means it's stabilised and has a strong ecosystem that requires little to no effort to get set up. And it still gets a lot of love with every Christmas release adding something desirable and new.

I also think it will require some immense innovation or paradigm shift to unseat Ruby/Rails as a de-facto framework for rapid web prototyping. I would still kick off a project with Rails in favour of trying to early-adopt some new approach to development.
