This reminds me of one of my favorite twists from the latest season of Silo
spoilers for Silo season 3
Each silo is run by the "head of IT" who is the only person who can talk to the super AI directing all the silos and can initiate a "safeguard" contingency in case anyone starts to learn the truth about the Silos.
The AI is actually just the trillionaire that built the silos and might have started the nuclear war that made them necessary (yes it is very fallout) getting woken up from cryostasis whenever something like that happens.
The show is very good and makes me want to read the books it is based on. It's good post-apocalypse slop and I gotta hand it to Apple TV for absolutely dominating the sci-fi tv scene lately.
