Philosopher William MacAskill argues senior staff at OpenAI and Anthropic genuinely believe AI could kill us all, citing years of public statements: Sam Altman called superhuman machine intelligence "probably the greatest threat to the continued existence of humanity" (2015) and warned the bad case is "lights out for all of us" (2023); Sutskever and Leike warned superintelligence could lead to human disempowerment or extinction; Jack Clark said AI has "a non-zero chance of killing everyone"; and Dario Amodei acknowledged significant catastrophic risk. The quoted commenter adds these fears are expressed privately too, not as a marketing stunt.
