I wish it was true as I reluctantly switched from Perl to Ruby and Python years ago when the job market demanded it. This article is flawed on 2 counts: the author is "director of engineering at ActiveState" and he bases his conclusion on the ridiculous TIOBE index. If you search Indeed.com for title:ruby, title:python, title:perl in the U.S the results are 1506, 847 & 137 respectively.
