Habitability is a relational, metabolic achievement, something living systems produce as much as they require. I've made it the first concept of planetary epistry, and I'm proposing it as the replacement for sovereignty.
How the word moved
In October 2025 it came in through Adam Frank, as what a planetary intelligence sustains across deep time. By April 2026 I was saying sovereignty had to give way to a concept one level deeper, and habitability was it. That's a big promotion in six months.
In May 2026 I read it as metabology, governed in space and time, and put my chips on the Strong Anthropic Principle. In July 2026 it became the first concept of Epistry, with three design problems hanging off it: governance, time and space.
In my words
"It is, in other words, a metabolic achievement."
from The Planetarity Syllabus. Habitability, Part I: Framing the Issue, 5 May 2026
"Sovereignty has to be replaced by a concept that’s one level deeper and way more important: habitability."
from The Planetarity Syllabus. Space, Part III: Alterity, and the Condition of Planetarity, 23 Apr 2026
"habitability is not a given; it is a relational, metabolic, planetary achievement."
from Habitability: Recasting the Planetarity Syllabus, 27 Jul 2026

Still open
The Strong Anthropic bet is pretty wild, and I said so at the time. I don't have a test for it beyond refining the hypothesis.
