A who’s who of tech tycoons will privately huddle with senators on Capitol Hill on Wednesday for a marathon brainstorming session about how lawmakers can regulate artificial intelligence. From a report: The daylong, high-profile gathering, featuring Elon Musk, Mark Zuckerberg, Bill Gates, Sam Altman and other tech figures, has its share of skeptics in both parties. Some senators lamented that the so-called AI Insight Forum is closed to the public and the media. Sen. Elizabeth Warren, D-Mass., said it would allow tech billionaires to lobby senators behind closed doors about one of the most critical issues facing the country and economy. Senate Majority Leader Chuck Schumer, D-N.Y., who organized the bipartisan gathering along with Sens. Mike Rounds, R-S.D., Todd Young, R-Ind., and Martin Heinrich, D-N.M., dismissed the criticism, noting that three public hearings on AI have been held and that the forums will also include labor and civil rights leaders, national security experts and academics.
