Ari Armstrong is favorably impressed:
The long-term benefits of an off-world colony to our lives would be enormous. Not only would such a colony open the solar system to commercialization, reaping unimaginable wealth from the development of vast resources and energy; it would also establish a new frontier with new possibilities for human liberty. Both in terms of industrial development and political innovation, a colony on Mars could be as important as were the British colonies in America. The future of human progress, and possibly even the future of true freedom, may depend on off-world colonization. In any event, human life certainly will be greatly enhanced by it.
I wish that more people understood this.
