Totally fair.. I am not claiming periodicity here :) I just wanted to use the "periodic table" as a visual metaphor. The goal is to outline a mostly orthogonal set of system design principles and illustrate cross-domain connections to students so that it is easier to compare trade-offs and discuss designs more precisely.

You keep doing you. It's a losing battle on my end. There will still be more Periodic Table of X on the internet after I've stopped yelling at clouds.
