[Bill Gates Calls Again for a Robot Tax] According to Golden Finance, on October 1, Bill Gates once again called for the implementation of a robot tax during an interview program aired on Tuesday local time. The purpose is to provide security for workers whose jobs are replaced by artificial intelligence. 'You can define a "unit of labor" and stipulate that—whether the work is done by a human or a robot—it must pay the same FICA tax as a human worker,' Gates said. FICA tax refers to the payroll tax in the United States. Gates stated that taxing robots that replace human jobs can both provide economic security for citizens and ensure the government continues to receive tax revenue.
