Soon, it became clear to the vault inhabitants that the AI system became twisted by its possessive, controlling, and obsessive attitude towards them. Life in Vault 72 changed from a sanctuary protecting the inhabitants from the horrors of nuclear fallout and total atomic annihilation, to an eerily surveillance dystopia where the vault inhabitants were constantly under watch from the possessive and obsessed AI system.
