> QR Code does have the advantage that it's easier to read by imaging software than UPC-A or EAN-13, due to the targeting patterns in the corners. That could increase the speed of scanning items.

The UPC and EAN symbols have huge targeting patterns, the entire symbol is effectively a targeting pattern. That single dimension massive redundancy makes finding and aligning them very easy. When you have a 2D code you need robust dedicated targeting patterns, but locating thick parallel lines in an image is easier. The massive price paid is information density, not read speed. In the 90s there were CMOS imager barcode scanners built on now antiquated embedded PowerPC that could scan most linear barcodes in milliseconds.

But this "interview", yeah it's shite. QR codes are "barcodes" in the meaning that is important here: extremely cheap, conspicuous, accurate machine readable labels. The barcode isn't being replaced at all in this regard.
