I personally believe we have so many programming languages because we have many problems to solve. When it comes to bad programmers, that's because they use and defend just one language. A good programmer is one that knows as many languages as possible and uses the correct language for the job. For example, if you need to create a nice UI then you use CSS and Javascript. If you need a simple server side language then you use PHP. If you need a program to be fast yet small then you use C. If you need scalable performance then you use Java. All of these languages have their purpose and using them correctly makes a good programmer.
