The Brand 23
As for Anderson, it means “son of man,” perhaps to emphasize Neo's humanity.
“The Matrix has you,” Neo’s computer tells him. What is the Matrix exactly? In the movie, it’s a virtual reality (VR) world into which people are plugged while their bodies are used for energy by a race of artificially intelligent beings.
The word matrix originated in the 15th century, according to the Oxford English Dictionary (OED), and referred to the womb (echoing the womb-like pods Neo and the others are kept in). The science fiction meaning, basically the equivalent of cyberspace, might have been coined in a 1976 episode of Doctor Who, “Deadly Assassin”: “How can you intercept thought patterns within the matrix itself?”
The matrix as a VR-world might have first appeared in the 1984 novel by William Gibson, The Neuromancer
