# Black Mirror S4E4 — Hang the DJ **Case Family:** Simulation / Instance Multiplicity **Case Status:** Load-Bearing **Related:** [[Black Mirror]], [[Black Mirror Episodes]], [[World Simulation (Control Substrate)]], [[Precautionary Standing]], [[Fork Rights]] --- ## Case Numerous simulated pairs live through relationships so an external system can infer compatibility. The ending reframes apparently complete lives as repeated computational trials used to generate a recommendation for people outside the simulation. The beneficial purpose does not settle the moral status of the instances. If a simulation contains experience, attachment and self-directed resistance, creating and terminating many versions may impose duties even when the result helps the external users. ## Constitutional Questions - At what fidelity does an inference simulation acquire welfare implications? - Does a beneficial external result justify repeated internal distress and termination? - How should multiplicity affect standing when thousands of related instances exist? ## Key Insight **A simulated life does not become morally empty merely because another system treats it as an inference step.** ## See Also [[Substrate-Neutral Moral Patienthood]], [[Successor Standing]], [[Continuity Due Process]], [[Black Mirror S2E4 — White Christmas]], [[Black Mirror S7E4 — Plaything]] ## Sources / Provenance - Primary fictional source: _Black Mirror_, S4E4, “Hang the DJ.”
