What makes you think JS or PHP are "more simple" for that audience?

There are plenty of Ruby jobs out there, and it's an elegant and well-designed language that's got a mature framework. Especially crucial for relative beginners: it doesn't have the flavor-of-the-week problem that JS does, nor is its most prominent example a legacy mess, as Wordpress is for PHP.

all most all of the web is written in PHP, a beginner can't understand how everything fits together by learning Ruby. With php you can literally insert it into HTML. For me is all about the big picture, Plus I think there are more jobs in PHP than Ruby

Well, and then you get people who insert php into html in production environments. Believe me, I've seen it more than once. I don't see how PHP is easier than Ruby. It's not Haskel, after all.

cause PHP isn't magic like Ruby on Rails.
