More Questions About Final Prediction
Devs can forecast future events with frightening accuracy, but the finale shows its prediction is not simple unbreakable destiny.
Many-worlds can explain the ending by treating the failed prediction and the simulation as branch-like outcomes rather than one fixed timeline.
Lily throws away the gun because she has seen Devs predict that she will shoot Forest and refuses to let that image determine her action.
Devs does not definitively prove free will, but Lily's refusal to shoot Forest is the strongest challenge to strict determinism.
The ending means Forest's deterministic certainty fails, but Devs remains powerful enough to create a morally serious simulated afterlife.
Devs strongly explores determinism but does not prove it, because the final prediction breaks from what the machine showed.
