I came across the following as somebody's tag line on a Microsoft forum but couldn't find out anything more. It suggests that...
"A programmer is just a tool which converts caffeine into code"
In this there was more than an echo of:
'A chicken is only an egg's way of making another egg' which is attributed to Samuel Butler (1613-1680). This idea is now commonly used in biology - not least by Richard Dawkins - to describe an organism as a gene's way of making more genes.
In short, nothing is as it may appear on the surface.
