With the rapid development of generative artificial intelligence across various industries, manufacturing is actively embracing this technology. Generative AI can create digital twins, simulating the operation of production lines; advancements in computer vision also enable it to handle more complex tasks. This implies that traditional jobs operated by blue-collar workers are at risk of being replaced. Experts suggest that a single digital supervisory twin could potentially replace multiple experienced blue-collar workers, as it captures their knowledge and expertise. Manufacturing companies need to pay attention to the impacts brought by generative AI and assist blue-collar workers in adapting to new forms of work.
