Jeff Atwood:

Some of the largest sites on the internet — sites you probably interact with on a daily basis — are written in PHP. If PHP sucks so profoundly, why is it powering so much of the internet?

The only conclusion I can draw is that building a compelling application is far more important than choice of language. While PHP wouldn’t be my choice, and if pressed, I might argue that it should never be the choice for any rational human being sitting in front of a computer, I can’t argue with the results.

Results are and should be what matters. There’s no point in writing extremely elegant code if it doesn’t work. There’s no point writing elegant code if it requires herculean efforts to deploy in production. There’s not even any point writing elegant code if it takes you twice as long unless you can actually justify that in maintainability.

The reality is that even code that feels vastly more elegant is often only marginally more maintainable than average code. There is a huge maintainability benefit going from lousy code to average code but from there it starts to rely more and more on domain knowledge and particular coding patterns than on the elegance of the code.

As developers we need to keep in mind that while theoretical excellence is a really important thing to investigate and pushing the boundaries of technology with new techniques and languages, but they’re not everything. When it comes down to it most of us are paid for results, not theories. If those results come from a clunky, out of fashion programming language then so be it.
