The post-human body is immersed in the world of extended reality. This is no longer just the "robot bride" and "open brother" that McLuhan talks about. Instead, it turns all metaphors into the full range of three-dimensional perception world that appeals to sight, hearing and touch. This era has finally recombined the technology and art that have parted ways from classical Greek culture. Some of the most outstanding art will be based on extended reality technology, which will also be used to produce the worst art junk, thereby contributing to consumerism. The reality that our eyes can see is the graphic representation produced after the abstract combination of all computer data. It is the light arranged in the infinite thinking space, a dense cluster of data, the combination of physical world and cyberspace.
