mid-1990s – 2000 — When transhumanism met mailing-list accelerationism
foomflops
A sourced timeline of Eliezer Yudkowsky’s AI predictions, their deadlines, and how they resolved.
Follow each prediction from its original source through its deadline and resolution. Every prediction and chapter has a permanent, shareable page with citations.
mid-1990s – 2000 — When transhumanism met mailing-list accelerationism
1999–2000 — Shock Level Four and open-source seed AI
2000–~2012 — From 'we will build Friendly AI' to early catastrophic risk warnings
2006–2012 — Debugging humanity, one very long blog post at a time
2013–2021 — those who can't build, align
2022–2025 — those who can't align, sabotage
2026 – present — the prophecy recedes; the apparatus grows
1996 → 2001; walked back.
“It's expected in 2035. (Oops, make that 2025.)”
1999 → 2010; falsified by events.
“To have a good chance of outracing nanotech, we should plan to develop a seed AI by 2010.”
1999 → 2020; falsified by events.
“The 50% point [for nanotech] may be 2010, or earlier. … AI at 2020 CRNS.”
2000 → 2023; falsified by events.
“Regardless of whether neural networks are Necessary, they are certainly Not Sufficient.”
2001 → 2011; falsified by events.
“…a hard takeoff occurs in SIAI's or Webmind's basement sometime in the next ten years or so.”
2001 → 2008; walked back.
“…the ‘hard takeoff’ ‘seed AI’ three-hours-to-transhumanity scenario.”
2001 → 2020; falsified by events.
“2005-2020 / peak at 2008-2010”
2001 → 2010; falsified by events.
“…reaching transhumanity sometime between 2005 and 2020, probably around 2008 or 2010.”
2002 → 2023; falsified by events.
“I would call it dead certain in favor of a hard takeoff… all economic, computational… indicators point straight toward it.”
2006 → 2023; falsified by events.
“But a neural network the size of a planet, given the same examples, would have failed in the same way.”
2008 → 2023; falsified by events.
“Intelligence is about architecture… architecture is mostly about deep insights.”
2017 → 2030; still open.
“If humanity survives to 00:00 GMT, Jan 1 2030, Yudkowsky pays Caplan $200; a bet at 2:1 odds in favour of doom.”
2021 → 2025; falsified by events.
“I'm happy to argue that there won't be a 4-year interval with world economic output doubling before then.”
2022 → 2025; came true.
“I'll stand by a >16% probability of the technical capability existing by end of 2025.”
2022 → open; still open.
“…doubling our chances of survival will only take them from 0% to 0%.”
2021 → 2025; falsified by events.
“…the World-Ending Company will be able to use the same tech to build a true self-driving car, which would in the natural course of things be approved for sale a few years later after the world had ended.”
2021 → 2025; falsified by events.
“this all sure does sound "pretty darn prohibited" on my model, but I'd hope there'd be something earlier than that we could bet on.”
2021 → 2025; falsified by events.
“if the world lasts until 2035, I could perhaps see deepnets becoming as ubiquitous as computers were in… 1995? 2005? would that fulfill the terms of the Prophecy?”
2021 → 2023; hedged: couldn't lose.
“I feel like I would indeed not have the right to feel very surprised if Codex technology stagnated for the next 5 years, nor if it took a massive leap in 2 years and got ubiquitously adopted by lots of programmers.”
2021 → open; still open.
“I think my sheer impression would be that we'll get $1B/yr waifutech before we get AI freedom-of-the-road”
