I can't think of a single phone that automatically opens links that are in QR codes. The worst it would do is just show a link to malware, wish you would have to manually click in order to download the malware.
AIs need to read it, so it could be a way to inject prompts on AI models.
Quite the opposite. That video by mattkc (iirc) repeatedly and unequivocally says that to make this work, he made his pc save the binary and explicitly run it using a python script, because doing it natively would be fucking insane
The 3DS used to be hacked using a QR code that was scanned using the game cubic ninja (it used QR codes as a medium for sharing levels). The interpreter had a basic memory safety bug, so you could trigger a ROP chain using a malformed QR code to get ACE. This was of course voluntary by the user (and cubic ninja was hard to get because it was not a commercial success) but that qualifies, I guess.
Then they found out the 3ds browser uses a WebKit version from 2003 and nowadays you just go to a website lol
