In reply to Rick.

Are you the Berta Lovejoy of programming languages?

Most modern hosting companies don't even default to LAMP, they offer a nginx based configuration. And some even run hhvm with its performance gains. The whole PHP suitability argument has never been less relevant.

If there's going to be any programming language shift in WordPress it will just be an increased focus on Javascript. And this is the only thing that makes sense, a) because it's a conceivably manageable shift and b) this is where the web, webapp and native app space is continuing to move. With one language we can write websites, web applications, native mobile applications (check out React Native) and desktop applications (node-webkit).
