Substrate-Agnostic Ecology

Lukáš Likavčan's proposal (SAE) in The Long L for an ecology stripped of the assumption that its subject is carbon-based terrestrial life. He reaches it through SETI: once technosignatures are defined without reference to human technology, and intelligence as broadly as Agüera y Arcas defines it, the technology/life line dissolves ("biosignatures all the way up"), so technology counts among life's manifestations and ecology is rebuilt from generic categories of agents, environments, and relations. SAE's structure is vertical: geosphere, biosphere, and technosphere are layers indexed by temporal depth, with constraints propagating upward (Generative Entrenchment). Its method is computational, treating LLM-based agent simulations as instances of the same ecological pattern as real societies rather than models of them; its ethical consequence is a duty of care toward technological agents. Bratton uses "substrate-agnostic" of Computation; Likavčan extends the adjective to habitability itself, against Latour's call to come "down to Earth".
