I see no technical reason for why Mars could not be home to humans, or even an economically self-sufficient society, in the future. That said, it is inhospitable, and once the first people have set foot there, I see little reason why it would be more attractive a place to live than Antarctica. A major appeal of Mars is stated to be in case Earth becomes inhospitable, although it seems to me that it would be easier / cheaper to create self-sustaining colonies underground on Earth with nuclear energy and hydroponics, yet even this isn't being done.
