WASHINGTON — Members of Congress want to regulate artificial intelligence, and Big Tech is watching — and lobbying. Senate Majority Leader Charles E. Schumer, D-N.Y., launched a major push on AI regulation late last month, promising his colleagues hearings and a series of “AI insight forums” that will bring top AI experts to Washington and eventually lead to the creation of draft legislation. Over the next several months, members of Congress — only a few of whom have any technical expertise — will have to choose whether to embrace a strict regulatory framework for AI or a system that defers more to tech interests.
