⚡️NEW: Anthropic's Jack Clark warns AI could push U.S. GDP from $30 TRILLION to $44 TRILLION, but humanity may have only a few years to establish safeguards before AI outpaces human control. He warned of a potential AI "singularity," urging global rules to prevent misuse in biological research and cyberweapons. The warning comes ahead of Anthropic's reported November IPO, which could value the company at $2 TRILLION.
