OpenAI and major AI firms urge US to slow artificial‑intelligence development

More than a thousand AI workers from leading companies—including OpenAI’s chief scientist, co‑founders of Anthropic, and senior executives from Meta and Google—signed a letter urging the United States government to back an international effort that would deliberately pace the development of advanced AI systems. The signatories warn that rapid progress could outstrip society’s ability to manage risks, and they call for mechanisms that give governments, companies and the public time to address safety and oversight concerns. OpenAI’s CEO Sam Altman has expressed support for a possible slowdown and pledged to cooperate with any government‑led initiative.

At Rio Innovation Week, investor Chris Rynning described the current AI surge as an “Oppenheimer moment,” urging coordinated governance to prevent unchecked advancement. European CIOs highlighted the growing importance of digital sovereignty, stressing the need to reduce dependence on foreign AI providers and to secure data and computing infrastructure. In Brazil, policymakers and industry groups emphasized AI sovereignty, calling for diversified supply chains, domestic computational capacity, and robust data protection. Nvidia announced a partnership with the Rio de Janeiro engineering council (CREA‑RJ) to provide AI training and consultancy, while debates in Brazil’s medical community examined the realistic timeline for autonomous surgical robots.

Collectively, these developments reflect a global push for responsible AI development, governance frameworks, and strategic investment in national AI capabilities.
