From the Wired story 40 Years on, the Barcode Has Turned Everything Into Information by Marcus Wohlsen:
... [Putting] barcodes on chocolate bars and instant oatmeal did more than revolutionize the economy, or the size of grocery stores. Thanks to bar codes, stuff was no longer just stuff. After a thing gets a barcode, that thing is no longer just itself. That thing now comes wrapped in a layer of information hovering just beyond sight in the digital ether. The thing becomes itself plus its data points, not just a physical object unto itself but tagged as a node in a global network of things. Barcodes serve up the augmented reality of the everyday, where everything can be cross-referenced with everything else, and everything has a number.
Haberman himself knew barcodes meant more than just a better way to manage supermarket inventory. He saw linguistics. He saw metaphysics. He also understood that those deeper abstract meanings held the key to barcodes’ radical practicality. “Go back to Genesis and read about the Creation,” Haberman once told The Boston Globe. “God says, ‘I will call the night “night”; I will call the heavens “heaven.”‘ Naming was important. Then the Tower of Babel came along and messed everything up. In effect, the U.P.C. has put everything back into one language, a kind of Esperanto, that works for everyone.”
