This was fun to read, but still very educational. There is a lot of hype around space settlement and the Weinersmiths thoroughly show all the little details that are very important, but do get glossed over in the discussion because people are overeager in dreaming of a space frontier.

My takeaway from the book: Let's conserve Earth first, take our time to develop a lot more understanding about space settlement and the advanced technology we might need, and then when we have sorted out everything here on this planet, then we might start thinking about colonizing this void out there that is trying to kill us. Makes sense to me.
