A Berkshire Hathaway shareholder wants a committee of independent directors to oversee risks associated with artificial intelligence at the dozens of companies in Warren Buffett’s conglomerate. Tulipshare, an activist investor group based in London, said on Tuesday it submitted a shareholder resolution for Berkshire’s annual meeting on May 3 to create the committee. It said improper use of AI could result in data leaks, privacy intrusions, business disruptions and human-rights abuses, and that Berkshire’s influence in many industries gives Buffett’s company a unique opportunity to be a leader in AI governance.
