I think this is more indicative of Rails falling out of favor that actual vanilla Ruby declining as a scripting language. Rails is Ruby's only real killer app framework, and it really isn't killer any more. It was pretty inevitable that enterprise Rails apps would go the way of the dodo once folks got wind of ActiveRecord's pretty awful scaling issues, and the fact that Ruby isn't overly performant compared to other popular scripting languages in and of itself. I think the focus on Python these days has more to do with the fact that it's often the language people learn first these days, and the fact that it has effectively supplanted Perl as the swiss army chainsaw of scripting languages. I think Javascript is popular due to the fact that it is essentially the native scripting/programming language of the modern web (or at least it will be until WebAssembly really catches on), and the ridiculous preponderance of decent frameworks that are out there now for that language.
