AI Leaders and US Officials Debate Calls to Slow Frontier Development
A debate over the pace of artificial intelligence development intensified after Anthropic CEO Dario Amodei published an essay calling for stronger safeguards and coordinated limits.
Amodei proposed three measures: placing independent evaluators inside frontier AI companies, coordinating standards among companies in democratic countries, and pursuing international agreements with authoritarian governments where possible. He said Anthropic would commit to outside evaluation. He emphasized that “pacing” would not mean stopping research, but allowing more time to test, align, and secure capable systems.
OpenAI CEO Sam Altman endorsed the approach, including independent evaluation and a federal safety framework. He warned that AI could create risks involving loss of human control or excessive concentrations of power. Google DeepMind co-founder Demis Hassabis and SpaceX CEO Elon Musk also supported Amodei’s broad direction, while noting that implementation details remain unresolved.
Political responses were divided. President Donald Trump rejected calls for a slowdown, arguing that federal powers and US leadership are sufficient and that slowing development could benefit China. Vice President JD Vance questioned whether industry requests for regulation could serve established companies’ interests. House Speaker Mike Johnson similarly opposed a moratorium but called for discussions balancing national security, competition, and model safety.
Other political figures favored stronger intervention. Senator Bernie Sanders supported arguments for pausing AI development, while former officials Pete Buttigieg and Kamala Harris called for safeguards, limits, and a responsible slowdown. Former FTC Chair Lina Khan stressed that existing consumer protection and product safety laws already apply to AI companies.
Former White House adviser David Sacks said companies may slow voluntarily but questioned their motives. Former Meta scientist Yann LeCun dismissed Amodei’s warnings. Nvidia CEO Jensen Huang, meanwhile, emphasized broad participation in America’s AI economy. The exchanges illustrate a policy divide over whether safety requires slower progress, stronger regulation, voluntary standards, or continued competition.
