| Dario Amodei · Anthropic | Argued AI development is moving too quickly and companies need to “pace the frontier.” Pointed to early signs of AI-assisted / recursive self-improvement and the recent OpenAI–Hugging Face incident as reasons for stronger safety measures and independent evaluation.“pace the frontier” | Warned that as AI capabilities rapidly advance, risks could become “very serious”, including dangerous capabilities such as biological-weapons assistance. Described future systems as potentially comparable to a “country of geniuses in a datacenter”, with serious security and societal implications — and framed risks in tiers: short-term (bias, misinformation), medium-term (increasingly capable models enabling harmful activity in science/engineering/biology), and long-term (agents becoming too autonomous and difficult to stop or control). |
| Sam Altman · OpenAI | Publicly indicated agreement with Amodei's call for deliberate pacing, saying similar discussions about pacing had already been happening inside OpenAI.“agreement with Amodei — pacing discussions already inside OpenAI” | Has said advanced AI needs safeguards and regulation (Senate testimony: regulation should incentivize AI safety while preserving benefits). OpenAI's Superalignment work — co-authored by Altman — explicitly states that superintelligence could be dangerous enough to cause human disempowerment or even extinction, and that systems much smarter than humans must be controllable and aligned with human intent. |
| Elon Musk · xAI | Responded very briefly, endorsing Amodei's warning/call for caution rather than rejecting it.“Dario is right.” | Has repeatedly warned about potentially dangerous advanced AI, including describing the possibility of a “Terminator future” at the 2023 xAI launch and calling for a pro-humanity approach. At the 2023 UK AI Safety Summit he said AI was an “existential risk” because humanity may face something “far more intelligent than us,” that it was unclear whether humans could control such a system, but that humans could try to guide it toward beneficial outcomes and that a third-party referee was desirable. |
| Demis Hassabis · Google DeepMind | Said Amodei's essay points towards the right path forward and reiterated his support for an industry-wide standards body for AI safety.“points towards the right path forward” | Said mitigating AI's extinction risk should be treated as a global priority, while also stressing uncertainty about timelines and that current systems are far from AGI. Describes his stance as neither dismissing risks nor being pessimistic about AI's benefits, and frames AI safety as comparable to other major global challenges. |
| Satya Nadella · Microsoft | Said the pursuit of superintelligence should be grounded in the principle that AI must help humanity and remain under human control. Supported deliberate pacing, while emphasizing AI's benefits should be broadly distributed rather than control being concentrated in a few organizations.“AI must help humanity and remain under human control” | His public emphasis has been on human-centered AI, responsible development, governance, safety, transparency and accountability. Has discussed how to control powerful AI systems and manage risks while realizing benefits; when asked about AI getting out of control, said if something becomes completely uncontrollable, “we shouldn't allow it,” arguing for alignment and control rather than simply stopping development, and that unintended consequences must be considered from the start with safeguards built into engineering. |
