“We all die. The goal isn’t to live forever, the goal is to create something that will.” — Chuck Palahniuk

Originally the AI suffix stood for archived intellect, however these days it has concretised to becoming an Augmenting Infrastructure — a place from which to branch out in many directions.

Within this site you will find self-contained material in the form of project posts and blog posts, but also external links ¹ to other work – my own as well as not.
