Zion, the Machine World, and the Matrix were the three concepts in the Matrix trilogy. They were important philosophical and worldview settings in the novel. Zion (The Matrix) was a simulation system of the real world, made up of machines and programs. It was the "real world" that hackers could enter. In this world, humans were controlled by machines and deprived of their freedom and ability to think independently. Hackers tried to break the simulation system and rebuild the real free world by rebelling against the machine world. The Machine World was a virtual world made up of machines filled with various machine programs and algorithms. The machine world and Zion were interconnected as a larger simulation system. In this world, machines controlled all the slaves and goods that humans regarded as machines. The Matrix was the highest control center in the machine world. It was a supercomputer made up of machines. The Matrix was seen as the real master of the machine world, and humans were only its tools and chess pieces. In the novel, the Matrix was a virtual existence composed of programs and algorithms. It controlled the entire machine world and controlled the fate of humans. In the novel, Zion and the machine world were related, and the Matrix was the controller of the entire machine world. Hackers tried to achieve true freedom and liberation by rebelling against the machine world and the Mother. In short, Zion, the machine world, and the matrix were important concepts in the Matrix trilogy. They constituted the complex philosophy and worldview setting in the novel, exploring human freedom, the relationship between reality and virtual reality, and the nature of machines and programs.
