The Pentagon has ramped up deployment of its artificial intelligence (AI) technology in a bid to match with China's pace. Its ambitious AI project, known as Replicator, aims to deploy thousands of inexpensive AI-enabled autonomous vehicles by 2026, which would force hard decisions about the AI tech's maturity and trustworthiness. While many countries are developing AI-powered weapons, concerns about ethical use and lack of regulatory oversight persist. The Pentagon's commitment to maintain human control over AI systems is being challenged by advances in AI technology that could reduce humans to merely supervisory roles.
