I think there are a lot of people on here who think that "conquering space" is a giant distraction from the many very real problems that exist here on Earth that can actually be solved by self-sustaining businesses.
My issue with Mars One was that it didn’t seem very credible in achieving its goals and that worries me that now people have been burnt by Mars One, they will not take a more credible organisation seriously if/when one comes along.
That there are real problems that exist here on the Earth somehow does not preclude space exploration. Space exploration and solving problems on the Earth are not mutually exclusive activities. They can both be done in parallel and sometimes one helps the other and vice versa.
