2D barcodes such as QR and datamatrix certainly have their place, but I wouldn't say they're "massively resilient" to failure.

The codes use reed-solomon ECC and the symbology spec has different levels of error tolerance ranging up to a max of ~30% errors. That's certainly robust but it still requires a controlled optical setup to avoid operator frustration. Sometimes, in some applications, a nice big 1D barcode is better. Your 150 meter postage stamp example is an extreme use case that requires a lot of setup to work properly.

This color barcode appears to be an effort from a respected institution to increase information density. It doesn't have to be immediately accepted by major manufacturers to succeed. It just has to solve some problems for some applications. I think it's a compelling new symbology.

I work in manufacturing too.
