Anthropic endorsed the petition at the company level, citing its own research showing that 80%+ of its codebase is now written by Claude and raising concerns about recursive self-improvement compressing the time between capability breakthroughs. The letter stops short of demanding a blanket pause, instead calling for mechanisms to throttle development when needed. Congressional proposals like the AI Kill Switch Act and a potential FINRA-style review body are gaining traction, while engineering teams are expected to face stricter testing environments, more red-teaming, and longer validation cycles regardless of regulatory outcomes. ## Full article daily.dev links to this article rather than hosting it.
