Friendly cross atlantic ragging aside; all languages, operating systems, programming paradigms and editors are just tools. You use the right tool for the job. People discovered that thousands of years ago. I don't see where the confusion lies.

For example, there is currently a dearth of genetic diversity. We are living in the period of time that has more species becoming extinct than at any other time in history.
