IBM CEO Arvind Krishna discussed the challenges of AI regulation, including President Biden's executive order. While acknowledging the imperfection of any regulatory framework, Krishna supports the mandate for AI firms to disclose safety testing to the U.S. government. He emphasized the need for corporate accountability for AI models, suggesting legal liability, but expressed concern over the disclosure of proprietary information. Krishna also advocated for a risk-based regulatory approach to foster open innovation. Amidst regulatory discussions, IBM has rebranded its Watson AI line to better compete in the business AI market.
