I think this is a pretty reasonable and balanced article, actually, and I think it straight-up admits what many instructors lie about: If you already can write a Hello World back-end in some other language/framework, and you're now learning Rails just so you can do Rails+React, that's a dumb waste of time. (I'd say the same thing about most frameworks for most purposes, but it's especially true with Rails. But doing Rails+React when you're already fast and competent with Rails, that's a very sensible choice in most situations.)
