Based on Folk theory, Media Equation, and AI literacy research, the study constructed an interview outline and selected 72 students in 4th and 5th grade in three primary schools located in the Minhang and Putuo districts of Shanghai (two in the Minhang district and one in the Putuo district) as the study participants for focus group interviews. The study found that the availability of voice interaction is an essential basis for children to judge the level of intelligence of a machine; additionally, chatting is also the starting point for young children to build a close relationship with AI. Although AI cannot replace their friends, it can become a friend to them. While children expect the future of AI to be beyond the current level of intelligence and emotion and to enable the full use of machines in multiple scenarios and various fields, they are also concerned about issues such as privacy breaches that devices may cause in the future and believe that technology should not develop outside of human control.
