600 Google Employees Tell Sundar Pichai to Just Say No to Military AI

Over 600 Google employees have signed a letter to CEO Sundar Pichai, demanding the company block the Pentagon from using its AI models for classified purposes. The Washington Post broke the news, and the numbers are worth sitting up for.

The organizers say many of the signers come from Google’s DeepMind AI lab — and they’re not just junior engineers. The list includes more than 20 principals, directors, and vice presidents. When that many senior people speak up, you can’t dismiss it as a few disgruntled interns.

The letter itself is blunt. According to the Post, it states: “The only way to guarantee that Google does not become associated with such harms is to reject any classified workloads. Otherwise, such uses may occur without our knowledge or the power to stop them.”

That’s a fair point. Once you hand over AI models for classified work, you lose visibility into how they’re actually deployed. Google’s own AI Principles, revised in February 2025, already prohibit using AI for weapons or surveillance that violates international law. But classified contracts create a black box where compliance is hard to verify.

This isn’t Google’s first rodeo with military AI backlash. Remember Project Maven back in 2018? That was a Pentagon contract using Google’s AI to analyze drone footage. Thousands of employees protested, and Google eventually chose not to renew the contract. The company also published its AI Principles at the time, explicitly ruling out weapons systems.

But things have shifted. The current geopolitical climate — with the US and China racing on AI — has pushed many tech companies closer to defense agencies. Google’s contract with the Pentagon reportedly involves providing AI models for analysis, logistics, and possibly targeting decisions. The classified nature makes specifics murky, which is exactly what employees are worried about.

Meanwhile, Anthropic — another AI heavyweight — is currently in a legal battle with the Pentagon over similar issues. So this tension is spreading across the industry.

I get why Google might want these contracts. Military funding is substantial, and the company competes with Amazon and Microsoft, both of which have deep defense ties. But the employee pushback shows that many people inside Google still take the “Don’t be evil” legacy seriously — even if the company’s leadership has quietly moved away from that motto.

Pichai hasn’t responded publicly yet. He’s in a tough spot: ignore the letter and risk internal morale cratering, or accept the demand and lose a lucrative contract. Either way, this story isn’t going away. The AI arms race is real, but so is the conscience of the people building the tools.
