There’s absolutely no guarantee he’s on the right track. Humans expanding away from Earth is as likely as us being able to rewrite the speed of light.
There’s no rewriting the fundamentals of reality. One really bad day and Mars colony is wiped out. How much damage we do here before getting there is a real concern.
Please, go on. I want to hear more about how thermodynamics can be waved away for “just an engineering project.”
This is what I mean. Obsession and success with engineering has titillated people to the point of blind faith. Externalities do not exist in their conceptual void. It’s become akin to unfalsifiable religious belief.
If humanity doesn't spend the resources on spreading humanity throughout the universe, then the resources will be spent on disposable plastic toys that fill landfills. It's not as if an edenic utopia is being despoiled for this boondoggle. Our environment isn't in its precarious state because of too much space travel. We're debating over the disposition of a tiny fraction of our dwindling material resources, negligible in the grand scheme.

If we have a limited period before climate doomsday, then we'd better get cracking on space travel before it's too late.
