# 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.**
