Microsoft CEO Defends Army Contract for Augmented Reality

Tech workers are increasingly uneasy about their employers' work with the US government, especially the military. Some protests have led to real change: Google last year decided not to renew a contract with the Pentagon to apply artificial intelligence to drone footage, after 4,000 employees signed a petition protesting the arrangement. Last week, a group of Microsoft workers published a petition asking executives to terminate a contract to develop augmented reality technology for the US military. "We did not sign-up to develop weapons, and we demand a say in how our work is used," the petition, which was published on Twitter, says. Monday, Microsoft CEO Satya Nadella rebuffed the plea.
