This isn't a bad idea, not at all. But it can cause a lot of problems with similar categories. For example, you say that Artificial Intelligence should go into Machines. But in most case, stories about AI are purely Science fiction. The same can be said about pretty much anything related to technology.

To synopsize, stories that would fall under Machines also fall under Science and Items/Objects (in most cases). I think the category isn't needed.
