I'm glad to see this. Switching to a new standard barcode format that can hold more data and enable better tracking of physical consumer goods seems like the sort of thing that will have a large number of small benefits pervasively in the economy, one of the many small improvements of human technological civilization that in the aggregate results in a better world today than in the past.

I also like the aesthetics of QR codes better than traditional barcodes. They do kind of invoke the look of a Go board partway through a game, which is more visually interesting than the boring straight lines of the traditional barcode.
