Non-toxic, grown materials cross cost-parity this decade
Biofabricated and non-toxic building materials — mycelium composites, low-carbon binders, bio-based panels — are on a cost curve that plausibly reaches parity with incumbent toxic materials before 2030. If it holds, the non-toxic choice stops being a premium and becomes the default, opening a large, spine-aligned market across the building and health gardens. Provisional; the cost data is not yet primary-sourced.
A coin-flip thesis on purpose. The upside is structural — parity flips non-toxic from a values purchase to an economic one — but the supporting signal (mycelium insulation) is itself only signal tier, so the honest confidence is 0.5.
To raise it: graduate the mycelium signal to verified with a primary cost/performance dataset, then add two more material classes on the same curve. We are allowed to be wrong here; we are not allowed to be vague (LD-08).
Position BKG to make the non-toxic spec the easy default the moment parity lands; pre-build the spec library and the citation trail now.
