Eh - Rails is good. Really good. And I don't think it is just _so_ flawed that another framework has to come along and make things better. It's also fast, has a great ecosystem, is one of the least buggy development environments, enjoyable to work with...
That said, Crystal needs a rails-like framework. And who knows - maybe it will come to replace rails as the most productive and enjoyable framework for web development. But it'll take a while, a long while, to replicate the robustness that rails has - and a lot of that has to come from a vibrant community.
But it's not changing any games - it's still just a web development framework, for a language that's not even at 1.0.
