There was once a programmer who worked upon microprocessors. "Look at how well off I am here," he said to a mainframe programmer who came to visit, "I have my own operating system and file storage device. I do not have to share my resources with anyone. The software is self-consistent and easy-to-use. Why do you not quit your present job and join me here?" The mainframe programmer then began to describe his system to his friend, saying: "The mainframe sits like an ancient sage meditating in the midst of the data center. Its disk drives lie end-to-end like a great ocean of machinery. The software is a multi-faceted as a diamond and as convoluted as a primeval jungle. The programs, each unique, move through the system like a swift-flowing river. That is why I am happy where I am." The microcomputer programmer, upon hearing this, fell silent. But the two programmers remained friends until the end of their days. -- Geoffrey James, "The Tao of Programming"
