Don't be too worried, As will the example of Cobol, There is enough legacy code remaining to keep it alive for al long time to come. Along with the legacy code, there is new Perl code being developed every day. Even if all Perl Development stopped today, it would be around another 10 to 20 plus years.

Also, I am not that worried about Perlmonks, *IF* something better comes along I am sure it will generate a following similar to Perl.
