>I can fully see them trying to add something like this to a DVD so you couldn’t watch it more than X times or as a built in self destruct if someone tried to do a 100% bit-rip of the disk.

that would be as effective as current DRM measures then, i.e. their shit is going to end up on a russian torrent tracker within hours after someone gets a copy, just as usual

DRM for hardware products, where tech like this would make sense, can already be made virtually unbreakable with existing cryptography and on-chip logic/ROM

Like self destructing object that is provable secure after a read x times seems interesting outside DRM.

For example a lot newer military hardware uses software to be more effective. So if the gear has to be abandoned for some reason a secure erase sounds useful.

How much better than is than current solution of a chip on a glass substrate storing a crypto key with a heating elements or explosive to shatter it dunno. Although glass being brittle makes making sure it does not break accidentally has design challenges.

Polymers tend to be more durable.
