Do you say the same thing when someone wants to make a movie, produce a video game, buy a sports team, start a social network, and so on? Why does this criticism always get levied against the Mars vision, which at least will have positive side effects like new tech, a lower risk of being exterminated by an asteroid, and something aspirational that we can look up to. I feel as though the anti-Mars thing is a meme that has gone around social media and people are just uncritically buying into that frame. Where's the anti-movies movement or the anti-sports teams movement?
