Andy Weir On Economics Of Sci-Fi And Space

"Before writing a single word of his new book Artemis, Andy Weir worked out the economics of a lunar colony."

Fun interview of Andy Weir by Tyler Cowen.  BTW, I was told that the interview contains some plot spoilers for Artemis, so don't read/listen to the interview until you've read the book. (I haven't read the book yet, so I'm also holding off on reading the interview.)
