Very interesting talk. this kind of talk spawn up every season...
few thoughts (from a simple self learned programmer with 11 years of Perl funny):

• Perl will survive until be able to run on 'modern' machines.
• and survive until can manage modern IT stuff: webservers, DB,

More. Perl plays very good job in several fields: in some of them it is loosing position. Especially on evil and self-referenced selfish environment like win32 win64.
I work heavely on such platform and running my CGI on modern version it is a pain. Good news are the frequent realeases of Strawberry Perl (32, 64, portable!).

If we love this language, and of course we love it, the TJPride observation is the more sad:

Perl is dead if you look at it from the viewpoint of how many new people are being taught to use it (not many).

I was caressing for long times the idea of writing a game where you can script your IA in Perl: teenagers love this stuff (there is one inside me..): i saw many peoples learning LUA to customize a great game like Battle for Wesnoth .

Some one is interested?
