“Space colonization isn’t real, it’s a utopian fantasy.”

I could say the same thing about the inevitably authoritarian and regressive variants of socialism the people saying this idealize.

Actually, space colonization is far more feasible than communism.

I agree with that, with some caveats. Communism is contra human nature; space travel is contra human biology. Which is easier to change, human nature or human biology?

The future is vast and our successors will find out. Probably will be changing a bit of both, to be fair.
