I've not yet seen a collection, in one place, of the various summaries, responses, and rebuttals around AI timelines via biological anchors. In the spirit of “EAs should post more summaries and collections”, I attempt to make said collection here.

I've bolded and put stars around what I consider to be core reading (i.e., what I'd suggest you read first), based primarily on concision but also based on importance, according to me. Note that this collection is not ordered chronologically.

Note also: I've edited this collection to include the posts highlighted in the comments.

Ajeya Cotra

• "Draft report on AI timelines" (2020)
  • This is the original "bio anchors" report
  • Some places where Ajeya gives more accessible overviews and discussions of bioanchors (h/t Michael Aird, see his comment thread below):
    • A ~40 minute segment of Ajeya's 80,000 Hours interview where she talks about AI timelines - 2021, audio
    • FLI podcast: Ajeya Cotra on Forecasting Transformative Artificial Intelligence - 2022, audio
    • Timelines for Transformative AI and Language Model Alignment | Ajeya Cotra - 2022, Q&A, video
    • Q&A with Ajeya Cotra - 2021, video
      • Though only ~1/4 of the time is spent talking about timelines
    • AXRP Episode 7.5 - Forecasting Transformative AI from Biological Anchors with Ajeya Cotra - 2021, transcript of an interview
• "Two-year update on my personal AI timelines" (2022)

  • (I'd recommend turning to the OK, here’s why all this matters section first)
  • Shimi, Collman and Perret (2023)'s "Review of 'Fun with +12 OOMs of Compute'"

Forecasting Community

Metaculus

• (These community forecasts aren't linked to Ajeya's bioanchors report in the same way as a summary or critique, but they seem relevant to the debate and have been cited in a couple of the above posts.)
  • "Date Weakly General AI is Publicly Known"
  • "Date of Artificial General Intelligence"

Rose Hadshar and the Forecasting Research Institute

• "XPT forecasts on (some) biological anchors inputs"
• "Who’s right about inputs to the biological anchors model?"
