It shows how fast things get to hang all over the place; walls and floors and roofs don't mean anything and as a result, it looks inevitably messy (like Mir was). The astronauts have puffed up faces, can't move fast, have to exercize a lot. None of those things are described in SF books, as they are not "glorious", but that's the way it is. Because of the nature of 3D storage and because of our inability to recognize 3D as well as 2D (spatial recognition), things get lost very fast.

Although as a space cadet I enjoy reading your observations, it frustrates me that the list of things we learned over 30 years ago with Apollo, SkyLab and later MIR goes on and on.
Yup, I'm so glad we've spent the majority of NASA's budget for 2 decades basically duplicating SkyLab and MIR. Not!
