I think there's a middle way: double-down on sending robots to space, which technologically and economically spurs innovation and sustainability on earth, that we might someday be in a position to send humans to space for extended stays.
Planetary Resources is going in the right direction. Capturing humanity's imagination is a good start; capturing their investment capital is what actually gets things done.
I'd second that. By no means would I want to see space exploration stop. I just don't think we should be looking to live elsewhere when we can't live here.
