| I. J. Good, 'Speculations Concerning the First Ultraintelligent Machine' | 1965 | First statement of the intelligence explosion: a machine that can design better machines leaves human intelligence far behind | the core mechanism |
| Bostrom, Superintelligence | 2014 | Set out slow, moderate and fast takeoff and the idea of a decisive strategic advantage for the first project to cross the threshold | takeoff speed as the key parameter |
| Aschenbrenner, Situational Awareness | June 2024 | Argued that automated AI research could compress a decade of algorithmic progress into about a year, and framed the race as a national security project | speed; state involvement |
| Amodei, Machines of Loving Grace | October 2024 | Described 'a country of geniuses in a datacenter' compressing 50 to 100 years of biological progress into five to ten | the upside case |
| Forethought, Preparing for the Intelligence Explosion | March 2025 | MacAskill and Moorhouse argued that AI could drive a century of technological progress in a decade, raising many grand challenges at once | breadth of consequences |
| AI 2027 | April 2025 | Kokotajlo and co-authors published a month-by-month scenario in which a superhuman coder leads to superintelligence within about a year, with race and slowdown endings | a concrete takeoff path |
| METR time-horizon measurements | March 2025 to April 2026 | The length of tasks AI agents complete doubled about every seven months, then faster; in April 2026 laboratories reported no dramatic speed-up of their own research | leading indicator and counter-evidence |
| Narayanan and Kapoor, AI as Normal Technology | April 2025 | Argued that diffusion is limited by institutions and that transformation will take decades | counter-anchor on speed |
