Google DeepMind AI safety researcher Alex Turner resigned after the company signed a Pentagon deal that he said lacked safeguards against killer robots and mass AI surveillance. Turner claimed he spent months urging stronger restrictions before leaving. Around 600 Google employees had reportedly opposed the agreement involving classified AI work.

A Google DeepMind research scientist has publicly detailed the reasons behind his resignation from the company, saying he left after Google signed a Pentagon deal that failed to include restrictions against killer robots or mass AI surveillance. Alex Turner, who spent more than two years working on AI safety at Google DeepMind, announced his departure in a lengthy blog post published on July 15, tracing months of internal efforts to influence the company's stance before ultimately deciding to walk away.

Pentagon deal without restrictions

The Pentagon confirmed in early May that it had reached an agreement with Google, alongside Microsoft, Amazon and OpenAI, for what it described as lawful operational use of AI capabilities. According to Turner, senior leadership at Google had repeatedly assured employees that the company would not sign such an agreement.

"Senior management had insisted that Google wouldn't sign. I disagreed with them, but they largely ignored my warnings," Turner wrote in his blog post. He added that the eventual outcome fell short of what he had hoped for. "Google still signed a deal handing over their AI without restrictions against killer robots or mass AI spying. Google's contract restrictions were even weaker than OpenAI's. At that point, I couldn't stay at Google in good conscience, so I left," Turner wrote.
