LAS VEGAS--The White House on Tuesday proposed regulatory principles to govern the development and use of artificial intelligence (AI) aimed at limiting authorities' "overreach," and said it wants European officials to likewise avoid aggressive approaches. In a fact sheet, the White House said federal agencies should "conduct risk assessment and cost-benefit analyses prior to any regulatory action on AI, with a focus on establishing flexible frameworks rather than one-size-fits-all regulation." The comments come at a time when companies are racing to integrate AI and deep machine learning into their businesses to remain competitive. However, the technology raises ethical concerns about control, privacy, cyber security, and the future of work, companies and experts have said. Michael Kratsios, chief technology officer of the United States, said at a Web Summit in Lisbon on Nov. 7, 2019: "The Chinese government has built an advanced authoritarian state by twisting technology to put censorship over free expression and citizen control over empowerment. Through their massive system of censorship, the Great Firewall, the Chinese government violates the privacy of every person in their country by monitoring online communications and blocking access to information. Yet, he added, "despite this and other grave and documented actions that run counter to the values of America, Europe, and our allies, countries around the world continue to consider opening their arms to Chinese companies in order to build critical infrastructure, like 5G, or develop key technology, like artificial intelligence.
