The Yatima Scale – Measuring civilizations by depth, not energy

The site sells the idea through strong typography, a dramatic hero and a clear equation (ηY = I_exploited / I_Bekenstein), which gives the essay an immediate intellectual hook. Clever framing — flipping Kardashev from 'how much energy' to 'how deeply you manipulate reality' — but most of the argumentative work is literature review (Barrow, Sagan, Smart). It's thoughtful writing dressed in a beautiful one-pager, not a new research tool; interactive calculators or empirical examples would push this past being just a persuasive blog post.
