This source, written by IT journalist Takafumi Makino, discusses how China rapidly deployed various artificial intelligence technologies in response to the COVID-19 pandemic. The author explains that China's approach of quickly introducing systems to the market, even if imperfect, aligns well with the development of AI, which benefits greatly from real-world data and continuous learning. Several examples of these quickly implemented AI solutions are provided, including health codes for managing movement based on infection risk, AI-powered analysis of medical images for diagnosis, automated delivery systems to minimize human contact, and AI phone systems for gathering public health information and updating business hours. The source also highlights that China's previous experience with agile development in other sectors and a general public acceptance of iterative technological improvements contributed to this rapid deployment and ongoing refinement of AI.
