No, I think it's just you... you must have a huge problem when using any GUI interface these days--"OK or Cancel? OK to what?? Cancel what??? I have no idea what it's talking about!"
This is modded insightful??? For any non-degenerate case, the buttons OK and Cancel will be placed on a dialog that provides the context of what they are about, so their meaning can still be inferred from the whole interface they are connected with. If you are really interested in the scientific basis of how all this works, search for any literature in the intersections of "semantics" and "human-computer interaction" - there's much more to it than the average developer knows about.
BTW, in most cases the recommended text for buttons in dialogs is to summarize the effect they will have if pressed (like "Save" or "Delete all files" or "Stop the autodestruction sequence"), not merely "OK".
