Future of Life Institute — campaign: Pause Giant AI Experiments Open Letter (March 2023): called for a 6-month moratorium on training AI systems more powerful than GPT-4. 33,000+ signatories including Yoshua Bengio, Stuart Russell, Steve Wozniak, Elon Musk.

NoteThe source document shows 31,810 signatures published on 22 March 2023, which is lower than the claimed '33,000+' for the same time period. However, the source does not list the specific signatories mentioned (Yoshua Bengio, Stuart Russell, Steve Wozniak, Elon Musk), so those cannot be verified from this excerpt. The call for a 6-month moratorium on training AI systems more powerful than GPT-4 is confirmed. The signature count discrepancy (31,810 vs 33,000+) represents a partial confirmation—the order of magnitude is correct, but the specific number is lower than claimed. This could reflect that signatures were still being added after publication, but as of the stated date (March 2023), the source shows a lower figure.
