It is fascinating how certain technologies have such a far reaching influence on what we do in our day to day lives.
About twenty years ago, Java language came into existence. The effort was led by Sun Microsystems with James Gosling as the father of the language. Java showed that way on how something could be both open source and yet have the absolute best quality. A zillion systems got built on it, thousands of open source APIs and frameworks got released based on it. I know there are pockets of loyalists of lot of other programming languages that claim a better programming model or performance or best practices enforced and engrained in these languages. Ruby-on-rails, Python, and the list go on.
