Several recent studies examined how machine automation and artificial intelligence (AI) will change the future of work. Some estimates predict these technologies could displace up to 30 percent of workers worldwide by 2030. One study was published by PricewaterhouseCoopers, an international company providing financial and tax services. It predicted about 38 percent of American jobs could be at high risk for automation by the early 2030s. In Germany, up to 35 percent of jobs could be at risk. The company said about 30 percent could be affected in Britain and 21 percent in Japan. The risk of being displaced will greatly increase for workers with less education.
