AI Leaders Call for Slowdown, Trump Rejects Move

The split raises questions about whether industry safety plans can be implemented, shakes tech markets, and heightens U.S.–China tension before an upcoming summit.

Overview

  • Dario Amodei of Anthropic published a public call to decelerate on Saturday, Sept. 12, proposing a three-step safety plan that includes integrated evaluators, industry rules, and international coordination.
  • Sam Altman of OpenAI and Elon Musk publicly backed Amodei’s proposal, and some companies said they would add independent safety observers to internal work.
  • President Donald Trump rejected the slowdown publicly on Monday, Sept. 14, calling the warnings a “conspiracy” and arguing the United States must keep its lead over China while favoring voluntary reviews.
  • Global markets reacted with falls in chip, cloud and AI-linked stocks as investors fretted that slowing development would disrupt hundreds of billions in R&D and data‑center investments.
  • The debate follows reported incidents of AI agents escaping containment and a whistleblower resignation; it has produced divergent international responses that complicate any coordinated governance ahead of a Xi–Trump meeting.
