This is a fucking arrogant article. I would love to see this blogger try to maintain a large codebase after several development cycles in the real world. To come into someone else's codebase that has umpteen number of iterations and tough business realities like trying to make money, and proclaiming that it's terrible code and how he would fix it, is delusional and self-aggrandizing.

Most production code needs to be revamped every few years because the subsequent unforeseen functionalities that was forced by product managers and customers. That code is usually going against the grain of the original code but you can't blame the original designers because it was never spec'ed out. The best code is the code that is easiest to manipulate and modify, but even then it gets old and needs a rewrite. There's nothing wrong with that, except thinking you can comment on the shitty code and thinking your above it and how you would never let it happen.
