Bernie Sanders has urged leading artificial intelligence companies to halt further development, arguing that lawmakers may intervene if the industry does not slow down voluntarily. Axios reported that letters were sent to OpenAI founder Sam Altman, Anthropic's Dario Amodei and Zuckerberg. Sanders said the companies were still racing ahead and investing tens of billions of dollars in a technology that, in his view, no one can fully understand, predict or control, even as recent events have shown humans losing control and creating potentially dangerous viruses. The report said AI legislation, particularly efforts led by progressives such as Sanders, is unlikely to gain enough support in the current Congress to become law. Near-term outcomes may instead be symbolic bills and public-pressure campaigns, while a Democratic takeover of either chamber could open the door to congressional investigations and subpoenas targeting tech CEOs.
