If we're talking about building websites, there's a dozen of languages that you can pick from and they are all fine for making a website of almost any complexity.
Yes, you personally will (likely) prefer one language over every other. That doesn't mean anything.
There are really really profitable websites out there written in PHP, Java, C++, Ruby, C++, C#, Pascal, Python, Go, LISP, Javascript, etc.
Maybe I should've qualified that better. Languages can be interchangeable in purpose, but not in process. By that I mean that sure, I can write a web backend in pretty much any language I choose, but the quality of that backend code and the rapidity with which I can deliver it will heavily correlate with the amount of experience I have with the language in question.
I disagree.
