All exploits stop working once they're patched.

  It’s a reference to bootrom-level exploits. The bootrom is burned into the silicon and can’t be updated. If one finds an exploit in there, Apple can’t patch it without new chips.

    But those still might or might not be persistent. If you need to once again obtain physical access to use your exploit every time the user reboots, it isn't persistent even if the involved exploits are are unpatchable.
