"Elon and Jeff" - you pretend you know these people, always a bad sign.
"Elon and Jeff"'s plan is to allow the Earth to die, while a few thousand billionaires and their servants escape to live on the dark, cold, arid, lifeless, poisonous, radioactive deserts of Mars, where in a few hundred years of living in domes, if every year the inhabitants produced civil engineering on a scale hundreds of times of anything ever done on Earth, there would be a climate so inviting that for a few weeks in a tiny portion of the planet, you could go outside without a protective suit.
We could take the quadrillion dollars it would take to make a self-sustaining colony on Mars for billionaires, and save the Earth's ecosystem from destruction.
And yet for some reason you advocate for allowing Earth to die. But "Elon and Jeff" aren't going to take you along. You and your family will die with the rest of us peasants, if you get your way.
