The US Justice Department's top antitrust official has warned tech companies working with artificial intelligence to fairly compensate artists, entertainers, and creators or face potential action. Assistant Attorney General Jonathan Kanter emphasized that without fair compensation, there would be no incentive for creators to continue producing work. This concern has been fueled by rising tensions between AI companies and artists, with lawsuits filed over the use of creative works to train models. Kanter cautioned that monopolizing creative works is monopolization, regardless of AI involvement, and the department is closely monitoring the industry.
