Future of Life Institute (FLI) — 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 claim states '33,000+ signatories' but the source shows '31810' signatures at the time of publication (22 March 2023). The claim specifies 'as of 2023-03' which aligns with the publication date. The difference of ~1,190 signatures (33,000 vs 31,810) represents a ~3.6% discrepancy. While the claim's rounded figure of '33,000+' could reasonably encompass 31,810 (both are in the 30,000+ range), the source's exact count of 31,810 is notably lower than the claimed 33,000+. The claim also lists specific signatories (Yoshua Bengio, Stuart Russell, Steve Wozniak, Elon Musk) but the source excerpt does not provide the full signatory list—only references to it and media mentions of Elon Musk. The core campaign details (6-month moratorium, GPT-4 threshold, March 2023 date) are confirmed, but the signature count is lower than claimed.
