A friend of mine suggested a book called "Simulacron-3" for me to read, before I decided to grab the book I did some research and realized that it has the same premise as "The Matrix" movie. I know Wachowski brothers did use some of Plato, Kant, Descartes work, they also explicitly said that they wanted to do Ghost In The Shell for real.
Hence my question, did makers of Matrix say explicitly anywhere that their work was also influenced by "Simulacron-3" novel?
