The Future of Space Exploration

I don't think we should be constrained even by science when it comes to our imagination in what might come. I do, half jokingly say there will be a museum on space built above Armstrong's on the moon. The book essentially is about astro politics and international relations but there is room in there to explore lots of fun stuff. Do you think we will see things like advertising in space, sports in space, all that sort of stuff?
