Since the first intelligent humans learned to draw symbolic art, writing has been evolving into two distinct purposes. One type of writing is functional. A list of names and birthdates functions as a simple communique.
Poetry is a different animal.
Poems serve to demonstrate an ability to convey abstract or complex ideas in a way that elicits emotion. In the Middle Ages, Gutenberg invented moveable type. Several hundred years later, we started using the typewriter. Up until this point, the only output was a standard typeface and the words from within the typist's mind. These are the former ages of writing.
