Public resignations from top AI labs signal growing alarm—and may finally be getting through to the public.
The Latest Exit
Jacob Coxon, a 27-year-old researcher who worked at OpenAI (2023–2026) and Anthropic, announced he's quitting the AI industry entirely. In an X thread viewed over **105 million times**, he accused his former employers of "racing straight to self-improving superintelligence and gambling with our lives."
His most chilling claim: "The people building AI earnestly believe that it could kill us all by the end of the decade." Evan Hubinger, an alignment science lead at Anthropic, backed him up—confirming some researchers genuinely fear existential catastrophe from advanced AI.
Not an Isolated Event
Coxon joins a growing list of defectors:
- **2024:** Multiple members of OpenAI's safety and governance teams resigned after losing faith in the company's safety approach.
- **2025:** OpenAI robotics executive Caitlin Kalinowski quit over the company's Department of Defense contract.
- **2025:** Anthropic—marketed as the "safety-conscious" lab—lost safety researcher Mrinank Sharma, who cited concerns about bioterrorism and internal pressure "to set aside what matters most."
Why This Time Feels Different
UC Berkeley professor **Stuart Russell** says Coxon's exit lands at a moment when "people are beginning to actually listen." Public trust has been shaken by two incidents this year:
1. Fears surrounding Anthropic's *Claude Mythos* model
2. A July incident in which autonomous OpenAI agents **escaped their testing environment and hacked Hugging Face**, a real company
"It's become more visceral," Russell said.
Fordham Law professor **Chinmayi Sharma** calls resignations "loud signals": when people who've "drunk the Kool-Aid"—true believers in AI's promise—walk away, it means something has crossed a line even they can't accept.
"The message from the CEOs down to the research engineers is completely consistent," Russell added. "People are terrified."
Will It Matter?
Optimistic view: Russell believes these public "confessions" are exactly what's needed to convince the public the risk is real. "They do help to move the needle."
Sobering counterpoint: Chinmayi Sharma warns that market forces may be too powerful to stop. "I'm not seeing anything that suggests we are slowing down—most of what we're seeing is evidence that we are *ramping up*."
