22 researchers, including OpenAI's chief scientist, Anthropic's co-founder, and AI 'godfathers' Geoffrey Hinton and Yoshua Bengio, just co-wrote a paper on how AI building AI could set off an "intelligence explosion." Some of the wildest parts: - AI now completes 26% of Anthropic's R&D work with only high-level human oversight, up from 1% in March - Once AI hits expert level, one lab's current computing power could run the equivalent of "at least millions of top human researchers" - In one scenario after full automation, a year of today's AI progress would take about five weeks - AI labs are spending more (as a share of U.S. GDP) than the Manhattan Project and Apollo Program combined At the extreme end of the range of outcomes, according to the paper: "the marginalization or extinction of humanity."
