Not just because nobody's moving to Mars any time soon, not even Elon Musk.
Not just because I'd be a terrible astronaut. I'd calculate the coordinates correctly, then open the airlock in an absent-minded quest for wheat thins.
No... because life on Mars is a godawful small affair. A long-term Mars colonist who spent his time knocking about in a suit on the surface would hit his lifetime radiation limit within a few hundred days.
A permanent resident would have to spend almost all of their time deep underground, protected by a shield of rock.
If you told me I had to do that on Earth, I'd probably say "as long as there are salsa clubs and I can play Starcraft."
Mars would have a tiny population of dancers and around 13 minutes of Internet lag. Gee, no thanks.
If we're lucky and smart, someone may get to go. And I hope they go to stay, because creating a second fully independent biology is the best way to understand what we must do to preserve life on Earth. But I'm happy to participate via awesome sky-crane-propelled robot.
