The application of digital twin technology to people in reality has given rise to the concept of"digital twins".Real people reflect twins,who are mirrors of real people.Digital twins meet people's liberation needs:the reality of digital twins completes the precise mapping from real people to twins,providing a reference for the liberation of real people,the reflective nature of digital twins promotes the integration of reality and virtuality between twins and real people,constantly inspiring real people to question themselves,and the generative nature of digital twins enables them to coexist with real people throughout their entire life cycle.The presentation of digital twins provides conditions for human liberation:the liberation of the body is manifested as the need for digital twins to"remove cover"and"repair and enhance"the body;The liberation of the mind and mind is manifested as the liberation of the mind and consciousness,which requires digital twins.The liberation of boundaries is manifested as the expansion of boundaries between humans and nature and between humans,which requires digital twins.The empowerment of digital twins provides a path for human liberation:to uncover the need for self-awareness and to uncover the external self.Self-transformation requires guidance,experience,and dream of self-liberation,creating oneself requires eternal liberation of time and infinite liberation of space.
