Ruby is about to get red hot. Again

I know this is deliberate bit of hucksterism, but come on, not very many people at all consider Ruby "the language of the web". For better or worse that would be JavaScript.
Even if you were just looking at the back end PHP has a bigger presence than Ruby.
At the end of the day, you are debugging javascript. From my experience, debugging is not 80% of the programmer job but more like 99%. And I feel adding a lawyer of abstraction is just making the job harder. Even if you find a good plugin to match JS to the actual Ruby source, it still feels very gimmicky.
BTW, I love Ruby and I want this to happen but it's not going to be. :{
Ruby/Rails needs a real answer to real-time front-end javascript frameworks. Grandiloquence does not inspire confidence on any project.
Edit: To elaborate, there are so many statements of "X is hawwwtt" or "Y is so hot", I cannot help but wonder if this post is satire.
