The advance of chatbots is evolving the human-machine interaction into the conversational mode, which has also stimulated people’s expectation of barrier-free communication between human and machine. However, when analyzing the essence of human communication, it is not diffcult to fnd that chatbots are unable to develop empathy due to their lack of physical bodies, nor to develop an ontological understanding of the everyday experiences of human beings. The distinct physical differences between human and machine means that angelic communication between them would be barely possible. However, as an intelligent tool with high efficiency, chatbots can satisfy people’s strong demand for technical services, and its application and development prospects are extremely broad. Considering the ethical safety risks and social consequences brought by artificial intelligence, people should try their best to avoid getting involved in the deep social emotional relationship with machines and focus more on their instrumental service functions. Therefore, by recognizing the differences between ideal and reality within the technology myths, people can choose the best way of developing chatbots based on the expected risk prevention and control, and restart the new chapter of human-machine communication.
