One of the reasons a theory of everything may elude many of our today scientists (I think people in the past may have thought to know the answer) is that science is based on the visible, the discovered, the facts. From this, ideas/theories can be built, but some input may be overlooked.

Take the binary system, it consists of ones and zeroes. The zeroes aren't much - really - but without them the system wouldn't function very well. In the binary system it is difficult to overlook the importance of zero because it plays such a prominent part in the system. Yet in the decimal system the zero can easily become seen as a less important player, at times even ignored.

If reality is a place where both the binary system and the decimal system have their place (and then some other systems as well), the number zero becomes completely snowed under. While the binary system cannot function without the zero, when looking for everything it is easy to forget zero's importance.

As far as structure is concerned, most TOEs try to deliver an ultimate place with a 1 in top, that is the attempt is made to bring everything back to a single unified field. The ideas make use of the decimal system in which the number 1 is placed in top (and where they forgot zero because it was easy to ignore).

In my opinion, the only TOE that can really be a TOE must contain both binary and decimal structures (and others). According to me, a unified field - everything can be brought back to a single platform - cannot exist. But if you believe in just that, you may remain focused/fixated for a long time. I believe a TOE can exist in which zero plays an important role too.
