Composability

Compositionality is the essence of Category Theory, and the whole point of creating PKC to ensure that one can leverage the mathematical insights of Category Theory to construct and evolve personally-owned Knowledge Containers. Mathematically, it is conceptualized as a form of universal construction, and in software engineering, it is often realized through universal data abstraction, such as monad. In hardware, it is achieved by modeling hardware system as some compositions of a specific universal components, such as Nand or Nor logic gates.
