Failing to Understand the Exponential, Again

Summary

Julian Schrittwieser (part of the AlphaGo team) argues that humans systematically fail to comprehend exponential growth, and this failure is particularly costly when thinking about AI progress.

Key Claims

  • Human cognition is linear: we project recent rates of progress forward linearly, systematically underestimating exponential growth.
  • AI progress is not linear: capability jumps happen at specific thresholds (emergent abilities), which are impossible to predict from linear extrapolation.
  • The “this time is different” trap: each time AI seems to plateau, skeptics conclude progress is over. This has been wrong repeatedly.
  • Counterpoint: exponential growth doesn’t always continue. There are S-curves and real limits. The question is where they occur.
