It's about the density of information, quality of preservation (eg. checksumming) and simplicity to decode.
Sure, QR codes are unlikely to be useful in 500 years, but if they have the above properties, they are just as good as anything else. If civilization endures, I am sure they'll be decodable in 5 centuries (whether they are preserved is altogether another matter).
