Timelines to the singularity

People have been dating the arrival of machines smarter than us since the 1960s. This page puts their calls on one line, from the mathematicians who first imagined an intelligence explosion to this summer's revised timelines, and reads each against what this site measures tonight. Nobody on it is crowned: the page shows who said what, when they said it, what would prove them wrong, and which way the evidence leans so far.

I · the timeline

The dates people have dared to give, on one line

Each row is a milestone; each mark, one forecaster's year for it. The glyph is how the forecast reads tonight.

When each forecaster expected each milestonea mark sits at the year forecast, a bar spans a stated range; hover for who said it, tap to open it

The scale is not even: the half century from 1950 and the half century from 2050 are squeezed so the years around now get most of the width (dashed lines mark where it changes). A call that gives odds, or bets against a date, without naming a year is listed under the chart. A forecast is placed at the start of its year, so one due by the end of this year sits left of today while its window is still open. Shaded: the years still to come.

HappeningRobin Hanson put less than one chance in a hundred on a single hand-coded AI leaping, without warning, from near impotence to overwhelming power. · 2008
Too early to tellEliezer Yudkowsky argued that an AI improving itself would most likely either stall or take off explosively, since a gradual, human-paced takeoff would need implausibly precise diminishing returns. · 2008
Too early to tellNick Bostrom judged it unlikely that the climb from human-level AI to superintelligence would take decades, and more likely that it would be fast or moderate. · 2014
HappeningFrançois Chollet argued that an intelligence explosion cannot happen, and that the first superhuman AI would be just another step in steady, roughly linear progress. · 2017
Too early to tellTom Davidson's best guess is that AI goes from matching human professionals at almost all cognitive work to far surpassing them in less than a year. · 2023
Too early to tellPaul Christiano put about one chance in seven on AI able to build a Dyson sphere by 2030, and about two chances in five by 2040. · 2023
Too early to tellPaul Christiano gave even odds on whether an intelligence explosion driven by software improvements alone is possible at all. · 2023
Too early to tellWilliam MacAskill and Fin Moorhouse give roughly even odds that AI improving its own software sets off accelerating growth in AI capability. · 2025
Too early to tellEge Erdil and Tamay Besiroglu doubt that AI improving its own software alone will set off an intelligence explosion, holding that compute and experiments bound progress. · 2025
Explosive growth
Too early to tellRobin Hanson's growth model implied that once machines can stand in for most human labour, world output would grow about ten times faster, doubling roughly every eighteen months. · 2001
Too early to tellPaul Christiano put about three chances in ten on a fast takeoff, expecting world output to finish a doubling over four years before any single-year doubling begins. · 2018
HappeningTyler Cowen guesses AI will raise annual economic growth by only about half a percentage point, because slow-moving sectors such as government, health and education act as bottlenecks. · 2025
Too early to tellWilliam MacAskill and Fin Moorhouse think it more likely than not that, once AI matches human researchers, a hundred years of technological progress follows in under a decade. · 2025
Too early to tellTamay Besiroglu expects explosive economic growth, above thirty percent a year, once AI can flexibly stand in for human workers. · 2025
Too early to tellExperts surveyed by Ezra Karger and colleagues expect that if AI outperforms humans on many tasks by 2030, US growth would rise to around four percent a year, against about two and a half percent in their overall forecast. · 2026
Too early to tellPhil Trammell argues that limits on splitting research across many AI workers could delay a technological singularity, though automating research would probably still produce an explosion. · 2026
Loss of control
Too early to tellStephen Omohundro argued that any sufficiently advanced goal-seeking AI, unless deliberately designed otherwise, will resist being shut down, copy itself and acquire resources. · 2008
Too early to tellPaul Christiano expected that, without solving intent alignment, AI failure would come as a gradual loss of human steering to optimised proxies, possibly ending in a sudden cascade. · 2019
Too early to tellToby Ord estimated about one chance in ten that unaligned AI causes an existential catastrophe within the next hundred years, the largest single risk he assessed. · 2020
Too early to tellJoe Carlsmith raised his estimate that power-seeking AI causes an existential catastrophe by 2070 from about one in twenty to more than one in ten. · 2022
Too early to tellCarl Shulman puts the chance that AI takes control of humanity's future at between a fifth and a quarter, depending on the day. · 2023
Too early to tellJan Kulveit and co-authors argue that if AI keeps displacing human labour, thought and consent across economy, culture and state, humans will probably lose effective control without any takeover. · 2025
Too early to tellDaniel Kokotajlo puts his chance of catastrophe from AI at around seven in ten, a figure he calls infamously high. · 2025
Too early to tellScott Alexander puts his chance of AI doom at about one in five, the lowest estimate among the authors of AI 2027. · 2025
Too early to tellEliezer Yudkowsky and Nate Soares hold that if anyone builds artificial superintelligence with anything like today's methods and understanding, everyone on Earth will die. · 2025

a forecast, at the year the timeline places itfrom the earliest year a forecast is placed at to the latestshaded: the years still to come

Each row counts forecasts, not people: a writer with more than one dated forecast on a row is counted for each, and the authors of AI 2027 appear both together and under their own names. A forecast that gives a range is placed, as on the timeline above, at its most likely year or else at the last year of its range, so a row does not show how wide each forecast is, and a row can begin later than the earliest year a forecast names. A step toward a milestone (a forecast of an early sign of it, not of the milestone itself) is left out and counted in the table. Each forecast is named on the timeline above and in the lists under it.

No middle or average is drawn. The marks on a row are not the same kind of year: some are a deadline ("by" a year), some a most likely year, some the last year of a range, and some a year the forecaster gave only some odds, in a few cases less than even. The forecasters do not all mean the same thing by a milestone, and the rows that are not in the forecaster table further down gather different claims on one theme. So a row shows how far apart the years are, not where opinion settles. The scale is the timeline's and is not even. This figure was drafted by a Claude model, made by Anthropic, and the heads of Anthropic and of rival labs are among the forecasters it draws; each is placed by the same rule, from its own record in this site's ledger of forecasts, and no placing was adjusted for anyone.

A machine that out-codes the best programmersAI that does AI researchGeneral or transformative AISuperintelligencethe range of years stateda mark set aside, tied back to the date it was madethe year the forecast was madethis year

One mark is one dated forecast of the milestones in the forecaster table: 37 in all, each linked to its record. The dashed steps are the year a forecast was made, so a mark higher above them looked further ahead. Because the scale up the side is not even, equal heights are not equal numbers of years: the table gives each forecast's years. A mark under the line marked this year names a year that has already passed; a mark on it names this year, which is not over. Neither scale is even: the years before 2020 are squeezed along the bottom, and the years before 2020 and after 2040 up the side (dashed lines mark where each scale changes).

Where one mark would cover another, the later is set beside it, to the right or the left, and tied back by a short line to the date it was made: 7 marks are set aside this way, some by several months, and no mark is set right of today. Read such a mark's date from the far end of its line, or from the table. No mark is named in the drawing: the table lists every forecast in the order drawn, left to right, with its writer. Not drawn: 3 steps toward a milestone and 14 forecasts that give odds or doubt a date without naming a year.

The marks fall toward the lower right because this site's list holds different people making different claims in different years, not because anyone here changed a date: no forecaster's earlier and later date for the same claim is on record, so the figure cannot show a forecast being brought forward and is not evidence that forecasts are converging. Where one writer has more than one mark on a milestone they are different claims, at different odds or on different conditions; each links to its record. A mark is the year the timeline places a forecast at, which may be a deadline, a most likely year or a year given only some odds, and a range bar may be a spread of odds or a plain "give or take". No trend line is fitted. This figure was drafted by a Claude model, made by Anthropic, and the heads of Anthropic and of rival labs are among the forecasters it draws; each is placed by the same rule, from its own record in this site's ledger of forecasts, and no placing was adjusted for anyone.

Beyond the dated calls

The pictures are illustrations made with image models, not evidence.

II · the calls whose time has come

The dates that have already come

Forecasts whose window has closed. Happening means the milestone arrived as said; slower than said means its date passed without it.

One line is one forecast, on an even scale of years. 5 forecasts have a closing date (the day this site set for checking it) that has passed: far too few to say how often such forecasts come true, so the figure counts and gives no rate. Slower than said means the date passed without the milestone. This site's ledger of forecasts has no word for wrong: a forecast that reads slower can still come true late, and one scored on a step says nothing final about the milestone itself. Where a forecast fell due within a year of being made, its marks touch.

A forecast with no closing date on this site's record is not on this calendar, even where the year it names has passed: there is 1 of those on the timeline, named in the table. The words are this site's reading on 2026-11-04.

III · where the forecasters sit now

The latest word from each forecaster

The most recent year each forecaster has given for each milestone, among forecasts made since 2023. The glyph is how the forecast reads tonight; each links to it. An earlier forecast by the same person may be a different claim, not an older view; all of them are on the timeline.

IV · what to watch

What would tell the fast story from the slow one

Each question names what this site reads tonight, and what a fast or a slow answer would look like.

  1. Does the length of task an AI can finish keep doubling as fast as the fastest forecasts need?

    Fast: Doubling at or faster than the pace the fastest scenarios assume. Slow: The doubling time stretching out, or the horizon stalling at a day or two of work.

    Tonight, doubling time of the task length108 days
  2. Does AI speed up the people who build it, when that is tested in a controlled trial?

    Fast: Trials showing developers finishing work much faster with AI than without it. Slow: Trials showing little or no gain, as the first one did.

    Tonight, speed-up in the latest controlled trial-4.0%
  3. Does any lab reach an AI that does the work of its own researchers?

    Fast: Independent tests showing agents doing more research work than the people overseeing them. Slow: The measure staying a lab's own claim, with no outside test.

    Tonight, a lab's own count of AI workdays per human workday3.10×
  4. Does the power for the largest training runs actually get built?

    Fast: The power drawn by the largest training runs keeps growing at its recent pace. Slow: The growth slowing as grid connections and turbines run short.

    Tonight, doubling time of the power the largest training runs draw419 days
  5. Does the spending on computing survive, and does revenue catch up with it?

    Fast: Spending staying high while the revenue it is meant to earn closes the gap. Slow: A cut in spending plans, or revenue falling further behind.

    Tonight, building and equipment spending against AI revenue4.38×
  6. Do open and Chinese models stay only a few months behind the best closed ones?

    Fast: The gap staying short, so no single lab can pull away. Slow: The gap widening as the leading labs hold their best models back.

    Tonight, months open models trail the best closed ones7.7 months
  7. Do the labs keep pulling their own brakes, pausing a run or holding a model back?

    Fast: Few brakes, and releases that go ahead as soon as the models are ready. Slow: More pauses and gated releases, of the kind a lab announces itself.

The grid is the outlook page's: how far capability goes, down, and how the rules settle, across. Each world is drawn over the cells this site gives it; the placing is this site's, a drawing of an idea, and no world is crowned. A glyph is one signpost: a claim the outlook tests each night, listed in the table.

A world reads consistent until a signpost in one of its cells fails. On 2026-11-04, of the signposts on the grid, counting one that sits in more than one cell each time, 8 are expected by both sides of the argument, 3 cannot be tested yet, 0 hold and 0 fail, and 2 cells have no signpost at all. So consistent here means not ruled out: it is no evidence that a world is on its way.

A managed explosion

Superintelligence arrives within a few years and the economy grows faster than ever, but governments and labs slow down enough to keep the systems checked.

Argued by the authors of AI 2027; William MacAskill and Fin Moorhouse.

Consistent with tonight's readings · its cells in the scenario grid

A long diffusion

AI keeps improving but spreads at the pace of earlier technologies, growth rises without exploding, and the disruption falls on particular jobs and places.

Argued by Benjamin Moll and Alex Imas; Arvind Narayanan and Sayash Kapoor; Charles Jones and Christopher Tonetti.

Consistent with tonight's readings · its cells in the scenario grid

Control slips away

Either a race produces systems nobody can check, or people are slowly made irrelevant as AI takes over the work, thought and choices that gave them a say.

Argued by the authors of AI 2027; Jan Kulveit and colleagues; Andrew Critch.

Consistent with tonight's readings · its cells in the scenario grid

The brake

Progress slows, either because people choose to stop it or because capability, power or money runs out first.

Argued by Arvind Narayanan and Sayash Kapoor; David Cahn; Jim Covello.

ideas the idea bank marks as built, by the decades betweenAain heavier type: the row the middle built idea falls in

This is the fiction lane: stories, not forecasts, and not evidence for any date on this page. It draws a different list from the works above: the Futures idea bank, 3746 inventions from novels and stories (Technovelgy: Science Fiction Timeline of Inventions (Bill Christensen); Not Boring: Sci-Fi Idea Bank (Packy McCormick)). Whether and when an idea was built is the bank's own mark, not this site's finding.

720 ideas are marked built with a date and are drawn. 2780 are not marked built and have no bar, so the figure shows how long the built ones took, not how long an idea takes: the ones still waiting would stretch it. Nor is it a guide to how long a story written today will wait. An idea from a recent story can only be here if it was built quickly, most ideas in the bank are not marked built at all, and nothing in the count says which of today's will be. The heavier row is where the middle of the built ideas falls, not a typical wait. Also left out: 126 built at a date the bank does not give, and 120 that existed before the story. Most of the bank's dates are decades, so the wait is counted in calendar decades, and an idea built a year after its story can fall in the next one.
