Did Black Mirror: Smithereens come true?
Largely, yes. Black Mirror: Smithereens (2019) has a P(n) of 100% on Nearfi's P(n) Board, our estimate of the chance its future arrives within 20 years. Of its 4 tracked predictions, 3 have arrived and 1 are arriving. Its central premise, 'A major social platform is deliberately designed, through notifications and feeds, to keep users returning compulsively, and its own leadership knows it', has arrived. The next prediction is estimated to arrive around 2029.
Smithereens invents no technology, so its ledger measures how well it described the present. It was right that platforms are built to pull people back, and that bereaved families struggle to reach a dead child's account. It was early on accountability: by late 2026 juries and states were forcing changes, but no chief executive has said what Billy says.

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.

| SMITH-4 | A platform can quickly assemble a profile of a person from their data and share it with police in an emergency, without a court order. Supporting: it shapes the siege, as Smithereen's staff profile Chris, but the story would survive without it. |

SMITH-1
A major social platform is deliberately designed, through notifications and feeds, to keep users returning compulsively, and its own leadership knows it.
Weight 5/5 · Core premise: the notification that distracted Chris and Billy's admission on the phone drive the whole episode.
Engagement-driven design is standard, and since 2021 leaked internal research, state lawsuits and a jury verdict have all treated compulsive use as a design outcome. Meta contests the framing and says its research was small and did not show causation, so the legal question of intent remains open. We date the claim from 2021, when internal research became public. 123

SMITH-2
A platform and its leadership are held to account, legally or by regulators, for the harm its design causes.
Weight 4/5 · Major: Chris's whole mission is to make Billy answer for the notification; the ending shows no accountability arriving.
A jury verdict (March 2026, under appeal) and a multistate settlement worth at least $12.1 billion over ten years (August 2026) have put money and design changes on the table. Meta denies wrongdoing, the settlement sets no precedent, and personal-injury and school-district cases continue. Accountability for individual executives, as in the episode, has not happened, so we mark the claim as arriving, with a median once appeals and the remaining trials resolve. 456

SMITH-3
Parents of a dead child cannot get into the child's social media account to find out what happened, even when they ask the platform directly.
Weight 3/5 · Supporting: Hayley's search for her daughter's password is the episode's emotional subplot but not its driving plot.
The case of Jools Sweeney, who died in April 2022, shows platforms handing over little and deleting data on schedule. UK law is now catching up: Jools' Law, in the Crime and Policing Act 2026, is meant to preserve a dead child's data, but a July 2026 analysis said it was not yet in force, and it does not by itself give parents access. 78

Weight 3/5 · Supporting: it shapes the siege, as Smithereen's staff profile Chris, but the story would survive without it.
Meta and Apple both publish emergency-request processes that let law enforcement ask for account data without legal process when there is imminent risk of death or serious injury. Meta has reported such requests since 2016. The episode's difference is that the company acts on its own initiative, which we have not verified in any real case. 910
