I don't think capital can sustain projects of this magnitude. Space is too harsh of an environment for delulu. We can hardly grapple with the idea that our actions on earth have consequences because of our condition. I like space stuff and I even like to create designs of starships, but I don't think we're in a position to reach for the stars just yet. Even if I'm wrong, we can't allow space fascism get started either. There is probably life out there and if space capitalism finds them, they'll try to pull another indigenous genocide and invent new forms of xenophobia to justify it.
None of our problems are technological. We have massive people problems. Building a new billions of dollar machine or trillions of dollar space station isn't going to disrupt the imperial core. The Gray Techno Fash won't suddenly become humanists because space.
Space life can be fun to think about, but techno futurism is a liberal fetish and tends to result in liberal fantasies if you don't decolonize your mind.
As long as there are white people, we have to keep having this talk. At some point they'll realize that white is a caste and hopefully give it up.
