Kan extension is a universal construct of generalized data type defined in Category Theory.
Proposed Application
Conceptually, we can use Kan Extension to generalize logic gates, specifically, two inputs, one output gates.
There are a total of 16 possible 2-input, 1-output, logic gates. They should be generalizable and represented using Kan Extension.
One may want to read this paper[1] by Marina on representing concepts universally.
Some useful tutorial on this subject
It would be helpful to learn enough about Limit/Colimit, Adjoint Functors, and Dynamical Systems, before studying Kan Extensions.

Richard Southwell on Kan Extensions
This video[2] is close to 6 hours of lengthy explanation. A large number of examples are presented in these hours.
This is about the time he started to formally introduce Kan Extensions. {{#ev:youtube|g_jEEwrpm9c|||||start=13600}}
