Google is undoubtedly the dream company for almost techie but it is rare to hear someone quitting Google job to protest against Mountain View, California company's decision. About a dozen Google employees have resigned from the company due to its involvement in a US Department of Defense project. According to a report by New York Post quoting Gizmodo, Google has signed a contract with Pentagon to build Artificial intelligence for the US military. This comes after nearly 4,000 employees signed a petition in April 2018, asking Google CEO Sundar Pichai to cut the company\u2019s ties with the controversial Project Maven. Employees have raised ethical concerns about the use of Google's machine learning and AI-technology in helping with Pentagon\u2019s drone warfare project. Many employees who quit have also written accounts of their decision. Google is helping the DoD\u2019s Project Maven \u201cimplement machine learning to classify images gathered by drones,\u201d according to the report. \u201cSome employees believe humans, not algorithms, should be responsible for this sensitive and potentially lethal work \u2014 and that Google shouldn\u2019t be involved in military work at all.\u201d Google's motto throughout has been 'Don\u2019t be evil', however according to some employees, this has changed, the report added. "Over the last couple of months, I\u2019ve been less and less impressed with the response and the way people\u2019s concerns are being treated and listened to,\u201d one employee who resigned told the tech news website. \u201cI realized if I can\u2019t recommend people join here, then why am I still here?\u201d In addition to the resignations, nearly 4,000 Google employees have voiced their opposition to Project Maven in an internal petition that asks Google to immediately cancel the contract and institute a policy against taking on future military work, the report said.
