Scores by kind of claim

Each kind of claim is scored on its own, out of 100: the share that held up, with the range it likely falls in. Fewer resolved claims give a wider range.

  • Factual claims

    Statements about the present or the past, checked against the record: did they hold up?

    79 72 85

    High confidence, 64 factual claims resolved. From 18 documents, 2019 to 2026; 19 documents sampled from 37 candidates found.

    Not scored: 32 unresolvable, 4 checkable only against their own records.

  • Predictions

    Statements about events outside the person's control, checked once they fell due: did they come true?

    80 72 88

    Medium confidence, 38 predictions resolved. From 7 documents, 2019 to 2025; 19 documents sampled from 37 candidates found.

    Not scored: 60 unresolvable. 13 more fall due later.

Prediction AI timelines and forecasting

“my guess is somewhere between 20 and 100 years, maybe closer to 50.”

Gary Marcus, interviewee 14 November 2019 EP25 Gary Marcus on Rebooting AI (The Jim Rutt Show)

Gary Marcus guessed that artificial general intelligence would arrive somewhere between 20 and 100 years from 2019, maybe closer to 50, and said this was a wide confidence interval.

Not yet due The date it refers to has not come.

What would count as true or false

Read the prediction as: AGI arrives between 2039 and 2119 (20 to 100 years after November 2019). 'Maybe closer to 50' (around 2069) is a secondary lean, not the test. True: AGI is broadly recognised as achieved (by consensus of independent AI researchers or major expert assessments, not just a company's own announcement) at some point in 2039–2119, and close to 2069 (roughly 2055–2085). Mostly true: AGI is broadly recognised as achieved in 2039–2119 but well away from 2069. Mostly false: AGI is broadly recognised as achieved shortly before 2039 (2036–2038) or shortly after 2119. False: AGI is broadly recognised as achieved before 2036, or credible assessments in 2119 show it still has not been achieved. Before 2039 the claim can be falsified only by early arrival. It cannot be confirmed until AGI arrives within the window. A company declaring that its own system is AGI does not count as achievement on its own.

Evidence

  1. What Is AGI? Artificial General Intelligence in 2026 | The AI Rankings The AI Rankings · 2 October 2026
    “Has AGI been achieved yet? There is no consensus that AGI has been achieved.”
  2. Wave 8: Timelines Forecasting Research Institute (LEAP panel) · 1 June 2026
    “Conditional on this occurring, the median expert forecasts a 50th-percentile year of 2050, with a 25% probability by 2039 and a 75% probability by 2065.”
  3. AGI Timeline: 74 Dated Predictions (2005-2026) agitracker.io · 29 October 2026
    “In AI Impacts' December 2024 survey of 1,580 AI researchers, the aggregate forecast gave a 50% chance of high-level machine intelligence by 2042 and of full automation of labor by 2098.”
  4. AGI Timeline: 74 Dated Predictions (2005-2026) agitracker.io · 29 October 2026
    “The Metaculus community median for the first general AI system to be devised, tested and announced was September 24, 2030 on October 29, 2026, with an interquartile range of March 2028 to August 2036.”

Reasoning

The prediction's window is 2039–2119, which is still in the future, and before 2039 the claim can be falsified only by AGI arriving early. As of October 2026 there is no consensus that AGI has been achieved (E1). So the early-arrival condition that would make the claim false (broadly recognised AGI before 2036) has not happened. Expert and forecaster timelines vary widely (E2, E3, E4), and they are forecasts, not outcomes, so they do not settle the claim either way.
