But why are filenames equated with spacetime coordinates? That doesn't make any sense - reflect on why you leaped to that analogy. The spacetime coordinates are the disk ID and sector number. We've been using operating systems that work a certain way for so long that we think filenames are like spacetime coordinates.

The analogy is location. file : directory :: person : geocoordinates. I thought it was a straight-forward analogy, but clearly I was mistaken.
