Factual AI timelines and forecasting

“Nobody said it would happen within 30 years, but now everybody is saying that.”

Ray Kurzweil, futurist, interviewee 9 July 2024 'The Singularity is Nearer,' Says Futurist Ray Kurzweil (Science Friday)

Among the forecasts he was describing, which averaged a hundred years, nobody said it would happen within 30 years, but now everybody is saying that.

Mixed Partly true and partly false in roughly equal measure.

What would count as true or false

Judge as of 2024-07-09. Two parts: (a) when Kurzweil made his 1999 prediction (human-level AI by 2029), nobody else predicted AGI within 30 years; (b) by 2024 'everybody' (read as experts and leading AI figures broadly) says AGI will arrive within about 30 years or sooner. True: the record shows essentially no other notable forecasters predicting AGI within about 30 years in 1999, and by 2024 a clear majority of experts and leading AI figures expected AGI within that window. Mostly true: in 1999 such predictions were rare and on the fringe (a few exceptions, e.g. Moravec), and by 2024 most prominent figures and surveyed experts held near-term timelines. Mixed: one part holds and the other fails, e.g. 2024 expert surveys show the median far from consensus, or several notable people in 1999 predicted similar timelines. Mostly false: there is a real shift toward shorter timelines, but both parts are greatly overstated (others such as Moravec or Vinge did predict it within 30 years, and 2024 surveys show widespread disagreement or median dates after 2054). False: the evidence shows many contemporaries predicted it within 30 years in 1999, and/or 2024 expert opinion did not mostly expect AGI within 30 years.

  11. Reason.tv: A Conversation with Author Vernor Vinge Reason Magazine (Reason Foundation) · 29 August 2011
    “In Vinge's 1993 essay "The Coming Technological Singularity" Vinge wrote, "Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended."”

Reasoning

On part (a), the evidence shows notable forecasters before 1999 with similar or shorter timelines: Vinge wrote in 1993 that superhuman intelligence would arrive "within thirty years" (E11, E1), and Moravec in 1988 projected that supercomputers would match the human brain before 2010 (E2). Reports that experts around 2000 expected AI to take about a century rest on Kurzweil's own account (E3, E7). On part (b), the 2023 AI Impacts survey's aggregate forecast gave a 50% chance of human-level machine intelligence by 2047, which falls within 30 years of 2024 and is thirteen years earlier than the previous survey (E5, E9). However, 50% by 2047 does not amount to "everybody": the survey reports a broad range of views (E10), and its forecast for full automation of labor is 2116 (E6). So the claim of a shift toward shorter timelines holds up, but both parts are overstated, and the result is mixed.
