Did Westworld come true?
Partly. Westworld (2016) has a P(n) of 64% 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, 'Androids that look, move, speak and feel like people, indistinguishable from them at close range, are manufactured and used as theme-park performers', is still far off. The next prediction is estimated to arrive around 2031.
Westworld's headline invention, androids no one can tell from people, is the part furthest from us. Its quieter bets have fared better: software characters that remember and improvise exist, and companies already hold large records of customer behaviour, while predictive risk scoring is common enough that the EU has banned its sharpest forms.

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.

WEST-1
Androids that look, move, speak and feel like people, indistinguishable from them at close range, are manufactured and used as theme-park performers.
Weight 5/5 · Core premise: the Hosts are the show's subject, and every storyline depends on them passing for human.
Home humanoids are now on sale, but 1X's Neo still relies on remote human operators for hard tasks, and robots remain clumsy in unstructured settings. The International Federation of Robotics, cited in a 2026 analysis, puts useful and widely accepted home androids about 20 years away. A robot that passes for a person up close would also need convincing skin, hands, balance and speech together, which no developer has shown. The range assumes nobody decides the product is worth building. 12

WEST-2
Characters in an entertainment setting keep memories, hold goals and improvise their own behaviour around the people they meet, rather than following fixed scripts.
Weight 4/5 · Major: the park only works because Hosts can improvise, and their growing memory drives the plot.
In 2023 researchers built a sandbox of 25 software agents that stored experiences, reflected on them, planned their days and coordinated a party from a single seed idea. Physical characters are further behind: Disney's Olaf walks and talks in a park, but public sources do not establish how much of his behaviour is autonomous. The software half has arrived in research. A commercial, fully autonomous character in a theme park, with persistent memory of individual guests, has not. 345

WEST-3
A single predictive system models each person's likely life, flags those it rates as high-risk and shapes their opportunities accordingly.
Weight 3/5 · Supporting: Rehoboam drives season three and the later seasons, but not the central story of the Hosts.
Individual risk scores already sort defendants, and a 2016 ProPublica analysis found one widely used tool was right about future violent crime only about one time in five. The EU AI Act now prohibits social scoring that causes unfair treatment, and bans criminal-risk predictions based solely on profiling. Those bans exist because the tools do. What has not arrived is one integrated system modelling everyone across every domain of life. What exists is a patchwork of separate vendors and agencies. 678

WEST-4
A company quietly keeps detailed records of its customers' behaviour while they use its service, to build models of them for its own purposes.
Weight 4/5 · Major: the guest data held in the Forge is the park's real purpose and drives season two.
A US regulator's staff report documented in 2024 that large social media and streaming companies collected vast amounts of user data, kept it indefinitely and fed it into algorithms and AI, often with weak deletion and little opt-out. The year of arrival is the year it was formally documented; the practice is older. The show's version, secret and aimed at copying minds, is more sinister than the commercial reality, which is disclosed in terms of service, and the 1X Neo shows the same pattern moving into homes. 91011
