Elon Musk says artificial intelligence needs "a referee" after tech titans meet with lawmakers

The nation's biggest technology executives on Wednesday loosely endorsed the idea of government regulations for artificial intelligence at an unusual closed-door meeting in the U.S. Senate. But there is little consensus on what regulation would look like, and the political path for legislation is difficult.

Executives attending the meeting included Tesla CEO Elon Musk, Meta's Mark Zuckerberg, former Microsoft CEO Bill Gates and Google CEO Sundar Pichai. Musk said the meeting "might go down in history as being very important for the future of civilization."

First, though, lawmakers have to agree on whether to regulate, and how.
