Oh! Oh! I know this one!

Telling someone else they’re doing freedom wrong!

Sure, in like four or five centuries maybe.

All that science fiction with colonies across the solar system by 20XX (or even the 2100s), its more fiction than science. Any sort of colony on Mars or the Moon or the skies of Venus or whatever is gonna have to recreate a biosphere from scratch. That alone would take decades upon decades of work – and that’s only really possible after we stabilize the biosphere we already live in.

First building an equilibrium with nature would give us the kind of expertise needed to actually make space colonies anything other than a pipe dream.
