Several Google DeepMind workers have resigned lately over a contract the company signed earlier this year that permits its AI in classified military environments. London research engineer Sofia Liguori left this week after three years, saying she felt ashamed of the military push and had lost faith in the firm's ethical values, with departure terms blocking lifelong criticism.

AI researcher Andreas Kirsch quit earlier this month, citing insufficient governance for safe military deployment and Google's lack of control or visibility once the Pentagon uses the technology. The pact covers any lawful government purpose while stating the AI should not enable domestic mass surveillance or autonomous weapons without human oversight, despite a letter from more than 600 staff urging the CEO to block classified operations.

Comparable deals were signed by OpenAI, Amazon, Microsoft and others amid Pentagon calls to become an AI-first force as quickly as possible.
