Perhaps this will make you feel a bit better about Perl popularity. The university where I work is part of a consortium of schools that purchased a certain brand of web software.
One of the things the consortium had to decide on was a common programming language. I don't know if they were offered a list of choices or everyone submitted their favorite language. Either way, when the votes were tallied, Perl had won.
How that compares to world popularity, I have no way of knowing. It seems, though, that Perl is not going to wither away just yet.
The Needs of the World and my Talents run parallel to infinity.
