I think ideas like these come together because of dialectics. By studying I'm learning how to think like those before me. Ideas, discoveries, inventions are a sum of formulated thoughts that came before them.

The reason I like the pizza metaphor in this case is because it's been used to falsely describe #Bitcoin. Bitcoin is a scaling denominator because the total supply adjusts to the market. Pizza doesn't do that, a pizza is only functional in a fixed ratio to its total, nutritional value.
