The check list of shit to-do to colonize something not on earth is pretty long. We still have to
-Find a more reliable way to get to space than sitting on an explosion.
-Figure out how to make faster ships so we get someplace cool in a reasonable amount of time. (Generstion ships are hard)
-Figure out the life support requirements for long term voyages.
-Figure out how to produce all required items on said colony (Looking at you STCs from 40k)
-Figure out how to come back to earth without packing twice as much fuel. (Or not, hopefully we don’t fuck things here up that baddly)
Finally, there is a time limit to get this shit done. Either climate change or kessler syndrome will punch our ticket and there will be no humans outside of our unfashionably small blue-green mud ball.
I applaud the optimism, I cant say that I have the same.
