Mark Nottingham looks at a barcoded bottle of wine, and the iSight embedded in a MacBook and thinks, Safari should be smart enough to automatically navigate to a page with details for that bottle (e.g., a map of where it was produced, its winery, tasting notes, and similar wines).
Hey, Mark, meet Bruce Sterling, who has also been looking at a bottle of wine:
So I am drinking from a machine-labeled, mass-produced bottle of industrial glass, with a barcode and legalistic health warnings, which exists in many hundreds of identical copies, and was shipped from Italy to California and offered for sale in a vast supermarket.
And yes, this bottle of wine has a Webpage. This is how it leans forward into the future world of the Spime. (pp 15-16)
