Twitter CEO Elon Musk said he met with Democratic Senate Majority Leader Chuck Schumer and other lawmakers and discussed measures to regulate artificial intelligence.

Musk told reporters after leaving the meeting, which lasted about an hour: "We talked about the future, about artificial intelligence and the economy."

Schumer told reporters he had a good meeting with Musk, adding: "We talked about Buffalo in New York — where Tesla has a big factory — and we talked about artificial intelligence."

Musk tweeted early on Thursday: "What affects the safety of the public has become regulated over time to ensure that companies do not fall short in dealing with these matters."

Schumer said he drafted and distributed "a working system that sets out a new regulatory framework that will prevent potentially catastrophic damage, while at the same time making sure the United States is advancing and leading the way in this technology."

Schumer's plans focus on transparency in AI systems, require independent experts to test technologies before public release, and require revealing people, places and methods involved in technology development.

Musk has been among the fiercest critics of the current rapid pace of AI development, signing an open letter last month with the Future of Life Institute calling on AI labs to pause for 6 months on training more powerful AI systems than GPT-4, a reference to the latest version of OpenAI's ChatGPT software.

There is growing pressure in Washington for AI regulations: Senate Intelligence Committee Chairman Mark Warner, a Democrat, sent a letter to top AI executives on Wednesday asking them to take steps to address concerns.

Commerce Secretary Gina Raimondo, a Democrat, told reporters Wednesday that the Biden administration is working "as aggressively as possible to figure out our approach" to artificial intelligence.
