Microsoft co-founder Bill Gates said during a speech recently that both governments and businesses need to prepare for a world in which humans will be competing with robots for jobs. Speaking at the American Enterprise Institute in Washington, DC, Gates said that as the costs for robots and technology go down, the demand for low-skilled jobs will also decrease. He said that governments might eventually have to reduce taxes to persuade big businesses to continue hiring human employees rather than investing in robots to fill the job. He went on to say that even high-skilled workers such as accountants, commercial pilots, astronauts and police officers are at risk of being replaced by AI-based robots in the future.
