This makes me think of Alexander's pattern language- according to that framework one of the key components of beauty is texture. I wonder if our dislike of untextured experiences stem from an unease at not knowing where the thing is hiding its warts.
That could be true. What it makes me think about is the danger of things that magically just work. Things that magically just work also may stop working for some reason and then you do not have an idea how to fix them.
