What is code? It is a static system of rules that can be dynamically operated upon. Because it is static, it can be contained. Because it can be dynamically operated upon, it can generate output. It has force and agency. In the language of Bonnitta Roy, it can move things. Code also consists of modules that can be detached and remixed. This is very different from the original usage of the word, which refers to the hefty volumes of the 19th century French and German civil and commerical codes. By coding capital, people have been able to contain it and multiply it. They can move it wherever they want. They can make it last longer. They can defend it against threats.
