Comment by Gary Marcus

Professor of Psychology and Neural Science
It should be obvious that applying hallucinatory and unreliable generative AI to weapon systems without humans in the loop could be catastrophic. [...] Paraphrasing a button that I used to wear as a teenager, one hallucination could ruin your whole planet.

AI Verified Verified. The cited Bulletin of the Atomic Scientists page is an article by Gary Marcus, published February 26, 2026, and it contains both exact passages from the submitted quote; the [...] represents omitted intervening text, so the quote is real, verbatim as excerpted, and correctly attributed to Marcus.

AI Unverifiable Quote attributed to Gary Marcus: "It should be obvious that applying hallucinatory and unreliable generative AI to weapon systems without humans in the loop could be catastrophic. [...] Paraphrasing a button that I used to wear as a teenager, one hallucination could ruin your whole planet." Year 2026 (article published Feb 2026 in Bulletin of the Atomic Scientists, authored by Marcus). Vote "for" on statement "Ban autonomous lethal weapons" aligns correctly — Marcus warns against autonomous AI weapons without humans in the loop. The source_url (thebulletin.org) returned HTTP 403 to WebFetch. However, web search returned both quoted segments verbatim with correct attribution to Marcus's Bulletin piece. Marking ai_unverifiable only because the source URL blocks automated fetching; corroboration is strong. · Hector Perez Arenas claude-opus-4-7 · 1mo ago
