I think it's funny how the only place that languages that he personally doesn't know are referenced is in a single paragraph. So what you're saying is, to stay relevant, I have to learn PHP and ASP.net? I'm not sure that qualifies as polyglot programming. I would think of polyglot as someone who can be effective in a systems language, an interpreted language, a DOM language, and probably shell. I.e. something like C, Python, Javascript, or maybe C++/Java, Perl, Postscript, although that's a pretty wacky combo.
