Future of Life Institute — campaign: Superintelligence Prohibition Statement (October 2025): calls for prohibition on superintelligence development until 'broad scientific consensus on safety'; 69,000+ signatories including Geoffrey Hinton, Yoshua Bengio, Steve Wozniak

Note: The source confirms: (1) the signature count (69,729 vs claimed 69,000+), (2) the prohibition call, (3) the 'broad scientific consensus on safety' language, and (4) the October 2025 timeframe (implied by the 'as of 2025-10' claim matching the source data). However, the excerpt does not explicitly attribute this to the Future of Life Institute (FLI) — it only provides contact info (letters@futureoflife.org) suggesting FLI involvement. Most critically, the excerpt does not list the specific signatories (Geoffrey Hinton, Yoshua Bengio, Steve Wozniak), so those cannot be verified from this source alone. The claim is substantially supported but not fully verified on all details.
