Did Black Mirror: USS Callister come true?
Partly. Black Mirror: USS Callister (2017) has a P(n) of 54% on Nearfi's P(n) Board, our estimate of the chance its future arrives within 20 years. Of its 4 tracked predictions, 1 have arrived and 2 are arriving. Its central premise, 'A conscious digital copy of a living person, with their memories and personality, is built from a DNA sample', is still far off. The next prediction is estimated to arrive around 2036.
The episode's immersive game world and its casual theft of a person's likeness are here in part; the thing it needs most, a conscious digital copy of a living person built from a stray DNA sample, has no credible path. The question it asks about how such a mind should be treated is already being asked about machines.

How this P(n) was calculated
P(n) is the chance that this work's future arrives within 20 years, by 2046. For each prediction we turn our estimate into a probability: arrived is 100%, diverged is 0%, and otherwise the low end of our 80% range counts as a 10% chance, the median year 50% and the high end 90%. Each prediction is weighted 1–5 by how pivotal it is to the story, and P(n) is the weighted average. P50 does the same by 2076. P(n), explained.

| CAL-4 | A realistic digital imitation of a real person's face and voice can be made and used without their consent. Supporting: the clones look and sound like the victims; the episode needs the likeness, but its horror lies in the minds behind it. |

A conscious digital copy of a living person, with their memories and personality, is built from a DNA sample.
Weight 5/5 · Core premise: every scene in the game depends on the crew being sentient copies of real colleagues.
Whole-brain emulation is still described as almost entirely theoretical, and only small animal brains have been simulated to various degrees. DNA cannot supply the copy anyway: it carries no memories, and the episode's route from a coffee cup to a mind has no real counterpart. Discarded DNA does get collected from rubbish for identification, which is as far as the real analogue goes. 123

Builders of a possibly sentient digital mind restrict how it may be treated, because it might suffer.
Weight 4/5 · Major: the episode is a study of what a tyrant does to minds that cannot leave, and what they are owed.
A 2024 paper by philosophers and AI researchers argued that some AI systems could soon be conscious or robustly agentic and that companies should begin preparing. Anthropic opened a model-welfare research programme in 2025 and let some Claude models end rare abusive conversations as a low-cost precaution. Anthropic itself says there is no scientific consensus that any current system is conscious, and no law gives a digital mind standing. 456

Consumer headsets and social VR worlds exist, but they are niche and the market has been shrinking. Meta's Reality Labs lost about 19.1 billion dollars on about 2.2 billion of revenue in 2025, cut roughly 10% of its jobs in January 2026 and closed three studios, redirecting money to AI and glasses. Full-sensory immersion of the kind the episode shows has no product. 78

Weight 3/5 · Supporting: the clones look and sound like the victims; the episode needs the likeness, but its horror lies in the minds behind it.
Deepfakes, named after a Reddit user in late 2017, made face-swapping routine, and a 2019 Deeptrace report estimated that 96% of deepfakes online were pornographic. Law has followed: the US TAKE IT DOWN Act, signed in May 2025, criminalises publishing non-consensual intimate imagery including AI-generated fakes, and platforms had to meet its removal duties from May 2026. This covers likeness only; the episode's copies have inner lives. 910
