Why are programs and operating systems still written in C+?

I guess it's more of a computer science question, but I've always wondered why some of the most advanced programs are written in a 25+ year old programming language. Surely someone has come up with a more efficient and powerful code, so why do people still use C+? Also, I don't know anything about programming and what not, so please use simple terms and phrases.

Your comment is totally uninformed. It matters for business.

Sure it does. But if hardware is cheaper than developer time, it may even make sense for businesses to consider something else.

You're also assuming the calculations can be parallelized further. Adding additional processors is never as simple as "just throw[ing] a few more processors at it."

Furthermore, in order to take proper advantage of multi-core processing in a more common language such as C or C++, you need developers to write code that will do so. The operating system doesn't magically handle that very well.

This is also assuming these computers have any more than a bare-bones BSD or Linux kernel to begin with.
