Bruce Sterling blasts the idea, beloved by certain "national greatness" types, of colonizing Mars:
I'll believe in people settling Mars at about the same time I see people settling the Gobi Desert. The Gobi Desert is about a thousand times as hospitable as Mars and five hundred times cheaper and easier to reach. Nobody ever writes "Gobi Desert Opera" because, well, it's just kind of plonkingly obvious that there's no good reason to go there and live. It's ugly, it's inhospitable and there's no way to make it pay. Mars is just the same, really. We just romanticize it because it's so hard to reach.
On the other hand, there might really be some way to make living in the Gobi Desert pay. And if that were the case, and you really had communities making a nice cheerful go of daily life on arid, freezing, barren rock and sand, then a cultural transfer to Mars might make a certain sense.
