I still don't understand why these people insist that there must be a "unified theory" (given my understanding that the "unified theory" has as its objective consolidating all of the forces under a single theory).

I think its a neat idea, as God is a neat idea, but I wonder why there is insistence that all of the forces tie together? All talk seems to be that it IS SO and simply will be found some day. There seems no room for it not being so.
