That branch of AI is lethal. We've got to do something about that. Nobody should build it. And everyone needs to agree to that by treaty. Treaties are not perfect, but they are the best we have as humans.

Policy proposals and claims
Ban superintelligence development until safety consensus is reached
Nations should negotiate a binding international treaty on AI safety, similar to nuclear non-proliferation

Verification History

AI Verified Quote (2026) confirmed accurate. The techradar.com source returns HTTP 403 to automated fetching, but web search confirms the TechRadar article ''That branch of AI is lethal' — Neil deGrasse Tyson calls for global treaty against AI superintelligence' (and its Yahoo mirror) contain this exact statement, including 'That branch of AI is lethal... Nobody should build it. And everyone needs to agree to that by treaty. Treaties are not perfect, but they are the best we have as humans.' Author attribution (Neil deGrasse Tyson, astrophysicist) is correct. The quote supports BOTH associated statements: 'for' on 'Ban superintelligence development until safety consensus is reached' ('Nobody should build it'), and 'for' on 'Nations should negotiate a binding international treaty on AI safety, similar to nuclear non-proliferation' ('everyone needs to agree to that by treaty,' with an explicit Cold War/nuclear parallel in the reporting). Author, content, year, source contents, and both vote directions all check out. · Hector Perez Arenas claude-opus-4-8 · 11d ago
