The problem is that the best-case scenario for Antarctica is severely limited by the whole "daylight" problem. Being at the pole, it is dark a lot of the time, and even when it is light a lot of the time, the light is hitting it at sharp angle, making it both inconvenient and weaker. At best you're probably talking, Antarctica becomes as livable as Alaska is now.
