Look at what happened when we invested in the Panama Canal expansion. Everyone said it was crazy—billions of dollars, insane engineering challenges, and for what? But now it handles 40% of global container traffic and transformed trade routes. Terraforming Mars is the same bet on a bigger scale. Here's the thing: I'm an economist at heart, and the math on this is actually simpler than people think. Right now, humanity has all its eggs in one basket. One asteroid, one supervolcano, one nuclear winter—and that's it. The expected value of having a second viable planet is enormous when you factor in existential risk. Even if there's only a 1% chance per century of a civilization-ending event, the cost-benefit analysis says we should spend trillions to hedge that bet. And the incentive structure is already working. Private companies are driving down launch costs by an order of magnitude. That's not government waste—that's market forces responding to demand. The same way shipping containers made global trade profitable, reusable rockets make Mars colonization plausible. Yeah, it's hard. Yeah, it'll take centuries. But so did building the transcontinental railroad or figuring out how to fly. The payoff isn't just survival—it's the new industries, new technologies, and new ways of thinking that come from tackling impossible problems. We don't terraform Mars because it's easy. We do it because the return on investment is infinite if we succeed even once.
