🚨 The guy who built Anthropic’s defenses against AI bioterrorism just quit.
Mrinank Sharma led Anthropic’s Safeguards Research Team. His job was literally making sure Claude doesn’t help bad actors do bad things.
His resignation letter: “The world is in peril. And not just from AI, or bioweapons, but from a whole series of interconnected crises.”
He also said he “repeatedly seen how hard it is to truly let our values govern our actions” inside the organization.
This is the company that positioned itself as the “safe” AI lab. The one founded specifically because OpenAI wasn’t careful enough.
Now their safety lead is walking away, saying the pressure to “set aside what matters most” is real.
He’s leaving to study poetry. Not joining a competitor. Not starting a startup. Poetry.
When your AI safety researcher chooses poems over production, that tells you something about what’s happening behind closed doors.
Today is my last day at Anthropic. I resigned.
Here is the letter I shared with my colleagues, explaining my decision.
