    Earth is certainly not "inevitably doomed," except billions of years from now when the Sun expands.  It's not even probably doomed.  It's just things will get a lot harder if we fail to address the challenges we face, both natural and self-inflicted.

    However, your claim that making human life multi-planetary is "highly improbable" is far removed from the reality of economic and technological processes already unfolding.  If civilization does not end in this century, people will be swarming the space on, around, and between Earth, the Moon, and Mars.  And that statement isn't based on some rosy optimism or Space Age historiography, but simply on economics as it's already unfolding.

    Thirdly, I reject your premise that human expansion into the solar system somehow entails neglecting Earth.  That's never been the reality of colonization.  Diaspora to the New World has been overwhelmingly beneficial to countries of origin, both economically, psychologically, and culturally.  Frontiers give people hope and options, stokes the imagination, inspires new ideas and approaches even among those who remain firmly rooted in the Old Country.  The same dynamic will play out with respect to space.

    Pour yourself into the future.
