Apple plans to open a manufacturing academy in Detroit later this year, bringing new job training opportunities to a city that has long struggled with poverty and high unemployment. The move is part of Apple’s $500 billion initiative aimed at expanding high-tech manufacturing and workforce development over the next four years. The Apple Manufacturing Academy in Detroit will provide free in-person and online classes designed to help small and medium-sized businesses integrate artificial intelligence and smart manufacturing techniques, according to the company’s announcement Monday.
