Modern web development doesn't use these, and mod_perl is certainly not recommended anymore - CGI still has its uses, but don't use CGI.pm. A modern webapp is written in Mojolicious or a Plack based framework, and they can all deploy transparently via a standalone server, or any PSGI or CGI server, or even mod_perl or fastcgi if you really need to.
Most people who develop web stuff with Python end up using FCGI/WSGI to use with nginx anyway, so I'm not sure what this complaint means.
An attempt to justify their rant with 1990s era perl examples
You don't have to use either of these. Was the last time you used perl in the late 1990s?
