Did Black Mirror: The Entire History of You come true?
Searchable replay of your own past and official inspection of your recorded life are both here, and wearables that log your day are on sale from Amazon and Meta. The one thing that hasn't come is the implant: the record lives on devices and servers, not behind your ear.

How this P(n) was calculated
Each prediction is weighted 1–5 by how pivotal it is to the story: 5 is the core premise, 1 is background detail. Arrived scores 1, arriving 0.5, everything else 0. P(n) is the weighted points divided by the total weight.
| Claim | Prediction · why this weight | Weight | Status | Value | Points |
|---|---|---|---|---|---|
| EHOY-1 | Ordinary people wear a device that continuously records what they hear and see, so their day can be replayed later. Core premise: everyone records everything they see and hear; the episode can't exist without it. |
5 | ARRIVING | 0.5 | 2.5 |
| EHOY-2 | People can search and replay a complete record of their own recent past instead of relying on memory. Major: Liam's obsessive re-dos of past moments drive the jealousy plot. |
4 | ARRIVED | 1 | 4 |
| EHOY-3 | Officials at the border can make travellers show them their recorded recent past. Texture: the airport security scene shows the world's norms but doesn't carry the plot. |
2 | ARRIVED | 1 | 2 |
| EHOY-4 | A small implant behind the ear records everything a person sees and hears and plays it back into their eyes. Supporting: the specific grain implant; the story needs recording and replay rather than this hardware. |

Weight 5/5 · Core premise: everyone records everything they see and hear; the episode can't exist without it.
Always-listening wearables that transcribe and summarise your day are on sale, and Amazon and Meta both bought makers of them in 2025. They mostly capture audio rather than continuous video, and the category has had public failures, notably Humane's AI Pin. Continuous audio-and-video lifelogging as a mainstream habit is the remaining step. 123

Weight 4/5 · Major: Liam's obsessive re-dos of past moments drive the jealousy plot.
Microsoft's Recall, which snapshots the screen and makes it searchable, rolled out across Copilot+ PCs in 2025 after a year of privacy delays. It covers what happens on a computer, not life itself, and other software is already fighting it: Signal blocks Recall from capturing its chats by default. 456

Officials at the border can make travellers show them their recorded recent past.
Weight 2/5 · Texture: the airport security scene shows the world's norms but doesn't carry the plot.
US border officers search travellers' phones and laptops under their border search authority, and the numbers have risen steadily since CBP began publishing them. It is still a tiny fraction of arrivals, and 'advanced' searches need reasonable suspicion under CBP policy, but the principle that your recorded life can be inspected at the border is settled. 78

EHOY-4
A small implant behind the ear records everything a person sees and hears and plays it back into their eyes.
Weight 3/5 · Supporting: the specific grain implant; the story needs recording and replay rather than this hardware.
Brain implants now let paralysed patients move cursors and turn attempted speech into text, but they decode intentions from a few brain regions. Nothing records full sensory experience from inside the head or writes it back to the visual system, and no lab has a credible route to doing so. External devices are doing the job instead. 910
