US Sen. Bernie Sanders is urging AI CEOs to pause AI development, warning that lawmakers will step in if no action is taken, Axios' Maria Curi reports. Sanders writes in a letter to OpenAI's Sam Altman, Anthropic's Dario Amodei and Meta's Mark Zuckerberg: "Pause AI development. It is not too late to avoid disaster. Stop building machines that humans cannot control ... Let me be very clear: If you do not take appropriate action now, my colleagues and I in the U.S. Senate will."
