Tech tycoons and lawmakers gathered in Washington, D.C. for a closed-door summit to discuss the regulation of artificial intelligence (AI). Billionaire Elon Musk called for an AI “referee” to ensure companies take safe and public-interest actions. Musk referred to AI as a "double-edged sword" that could have disastrous consequences. Mark Zuckerberg of Meta stated that Congress should engage with AI to support innovation and safeguards. Lawmakers are increasingly calling for federal regulation, including the rise of deepfake content ahead of the 2024 election. Key issues discussed included AI's impact on the US economy and potential job losses. Senate Majority Leader Chuck Schumer described the meeting as the start of bipartisan AI policy legislation. However, the details and timeline for legislation remain unclear. Despite concerns, Musk downplayed risks associated with self-driving technology. OpenAI CEO Sam Altman expressed concern about "deeper AI" with human-like capabilities. The meeting drew criticism from Republican Senator Josh Hawley, who questioned its progress. Musk and Zuckerberg appeared in the same room for the first time since their highly anticipated "cage match" plans fell through. In March, Musk called for a pause in AI development due to potential risks. Altman has called for guardrails on the AI industry. The meeting endorsed the idea of government regulations for AI, but there is little consensus on what it would look like. Senate Majority Leader Schumer is working on legislation but acknowledges the difficulty and complexity. The meeting aimed to provide senators with direction for meaningful regulation. Congress has a poor track record in regulating new technology. Tech leaders and lawmakers discussed various topics, including existential risks, closed vs. open source AI models, and feeding the hungry. The creation of a regulatory agency was considered likely. Google CEO Sundar Pichai endorsed Washington's involvement. Some senators criticized the closed-door format, arguing for public testimony from tech executives. Concerns were raised that the meeting favored big firms over the broader public. Major tech companies express support for AI regulations, but there is little agreement. Concrete proposals have been introduced, including disclaimers for AI-generated election ads. Urgency was highlighted in relation to the upcoming presidential election. Some Republicans are cautious about following the EU's comprehensive rules for AI.
