In 2023, hundreds of scientists and leaders, including two of the three “godfathers of AI,” signed a statement saying that “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”10 In 2025, nearly 150,000 signatories called for “a prohibition on the development of superintelligence, not lifted before there is broad scientific consensus that it will be done safely and controllably, and strong public buy-in.”11
