"Java is dying" is wishful thinking. It's not the case, but we can only hope it will be. Currently, it does a good job of marketing to developers too good for Ruby and Python and not good enough for C.
Welll, the reasoning behind it might be from two facts - a) Ruby and Python both are far better beginner/learner languages than Java & others - I mean, if some kid wanted to learn programming, I'd suggest to start in those because they don't have distracting boilerplate; and (b) other things being equal, Java does get you better execution performance than Ruby/Python; not on C level but it's halfway in between.
But still "developers too good for Ruby and Python" is an interesting statement; IMHO the only ones who'd claim to be 'too good' for Python/Ruby would be authors of their own languages or maybe the hardcore Lisp or Haskell crowd.
