Leaders of top AI companies say the artificial-intelligence industry should slow its fast-moving development to give safety measures time to catch up. Without such a slowdown, Anthropic CEO Dario Amodei warned that AI could be capable within six to 12 months of leading a swarm of agents that could take over the entire internet.

HONG KONG (AP) — Asian shares were mostly lower Monday as shares of AI-related stocks, including Open AI investor SoftBank, declined following calls from Anthropic and OpenAI to slow AI development for safety.

U.S. futures edged lower, while oil prices gained more than 2% as worries grew over global oil supplies after Saudi Arabia shut down a major oil pipeline used to help bypass the Strait of Hormuz after it was attacked.

South Korea’s Kospi lost 3.3% to 6,684.37. Japan’s Nikkei 225 index slid 0.8% to 63,492.99. Shares of Japanese investment conglomerate SoftBank Group, a key investor in OpenAI, plummeted 10.7% after OpenAI CEO Sam Altman backed Anthropic’s CEO Dario Amodei in his calls over the weekend that the AI industry should slow down to ensure its safety.
