Japan confronts the dark side of its teenagers’ AI addiction

A recent case in Hachioji, Japan, where five teenage girls allegedly severely beat a boy and then used artificial intelligence to determine how much money to demand from him, has highlighted concerns about adolescent AI addiction. Experts believe this incident, along with a separate high-profile case involving a sporting celebrity arrested for assaulting his daughter, reveals a disturbing trend of Japanese adolescents turning to AI for guidance, even in criminal matters, instead of using their own judgment.

A recent case in Hachioji, Japan, where five teenage girls allegedly severely beat a boy and then used artificial intelligence to determine how much money to demand from him, has highlighted concerns about adolescent AI addiction. Experts believe this incident, along with a separate high-profile case involving a sporting celebrity arrested for assaulting his daughter, reveals a disturbing trend of Japanese adolescents turning to AI for guidance, even in criminal matters, instead of using their own judgment. The boy sustained serious injuries, and the five girls are accused of the attack. This pattern suggests a growing reliance on AI among Japanese youth, raising questions about its broader social impact.
