Bernie Sanders Tells Meta, OpenAI and Anthropic to Stop Building AI Humans Cannot Control

The US senator sent letters to three of the most powerful AI companies warning that Congress will step in with regulation if they keep moving at their current pace.

Key points

  • Senator Bernie Sanders wrote directly to the CEOs of Meta, OpenAI and Anthropic in 2025, calling on them to halt AI development.
  • Sanders warned that AI capabilities have reached what he called a critical risk threshold.
  • He argued the companies are losing control over the technology they are building.
  • The letter threatens Senate regulation if the companies do not slow down voluntarily.

Bernie Sanders has had enough. The Vermont senator sent letters to the heads of Meta, OpenAI and Anthropic calling on them to stop developing artificial intelligence, a broad term for computer systems that can learn, reason and generate text or images on their own, until better safeguards exist.

The letter, first reported by The Guardian, takes a blunt position: the companies are building systems too powerful for anyone, including their own engineers, to fully control. Sanders called this a "critical risk threshold" and said that threshold has already been crossed.

What exactly is Sanders asking for?

He wants a pause. Not tweaks to a safety policy or a government review panel. A stop.

Sanders addressed his letters to Mark Zuckerberg at Meta, Sam Altman at OpenAI and Dario Amodei at Anthropic. These are three of the companies most responsible for the large language models, the technology behind chatbots like ChatGPT, Claude and Meta AI, that have spread across workplaces, schools and phones over the past two years.

His argument is straightforward: the companies have moved faster than their ability to understand what they are building. When the people creating a technology say they cannot fully predict or control what it does, that is a reason to stop, not speed up.

What happens if they ignore him?

Sanders threatened Senate regulation. He did not outline a specific bill, but the warning signals that at least part of Congress is willing to set rules rather than wait for the industry to self-govern.

That matters. The US has so far taken a lighter touch than the European Union, which passed a formal AI Act in 2024 setting legal limits on high-risk uses of AI. A push from Sanders, even without immediate legislative support, keeps that pressure visible.

Should ordinary people care about this?

Yes, because the technology Sanders is talking about is already in daily life.

AI systems now screen job applications, help doctors flag medical images, write customer service replies and generate news summaries. If the people building those systems admit they cannot fully control them, that is a problem for everyone who uses them, not just policymakers.

Sanders is not a tech insider, and his letter does not propose a technical fix. What it does is put three of the most powerful technology companies on notice that "move fast" is no longer a free pass.

What to watch for

Watch for public responses from Meta, OpenAI or Anthropic. So far none of the three companies has replied publicly. Watch also for whether other senators or representatives join Sanders or distance themselves from his position. And watch for any White House comment, since the current administration has signalled it wants less AI regulation, not more.

If you work somewhere that uses AI tools to make decisions about people, this debate will eventually reach your workplace. The question of who is legally responsible when an AI system causes harm is still largely unanswered.
