Nah…

Barcodes are easy and cheap to read in a way that QR codes aren’t (particularly complex ones)

Any old cheap laser scanner will read a barcode and they can be made at large sizes e.g. how Aldi use them on products in the UK to make self scan faster

QR codes need a camera, their complexity goes up as more data is encoded in them so require better cameras especially is high speed situations

They both have places in the world and will co-exist for years to come
