On April 28, hundreds of AI researchers from Google, a subsidiary of Alphabet, signed a letter urging Alphabet CEO Sundar Pichai to reject the use of the company's AI systems in classified U.S. defense missions. According to Jin10, the statement expressed concern over ongoing negotiations between Google and the U.S. Department of Defense. The letter comes amid legal disputes between the Pentagon and Anthropic over the application of AI in military settings. The Pentagon is seeking to remove Anthropic and its Claude AI tool from the U.S. defense supply chain and is looking for new tech giants as AI partners.
