What is the Wired in Serial Experiments Lain?
The series defines the Wired precisely: the sum of human communication networks, created with the telegraph and telephone and expanded by the internet, a plane that might, the story proposes, be coupled to the Schumann resonances, a real property of the Earth’s magnetic field, so that human minds could communicate with machines, and each other, without interface at all. Inside that premise the show builds its plot machinery: Protocol Seven, a next-generation network protocol into which engineer Masami Eiri has secretly written himself; and the Knights of the Eastern Calculus, a hacker order, their name a nod to the Knights of the Lambda Calculus, working to dissolve the boundary between the network and the world.
