Programming, writing, math, art are all ways I use to structure my thoughts and to test and cement my understanding.
The idea that these domains are limited by how fast I might type, or sketch are fantastical.
In all cases my ability is fundamentally limited by my understanding of the subject before me.
As soon as I understand something, actually know it, then capturing it's essence in code, in prose, through theorems or in medium cannot be a chore, because it must already be done.
