Southack, your criticism is misguided. It is not "silly" or "absurd" to attempt to make General Relativity and Quantum Mechanics compatible theoretically, since the actual Universe appears to satisfy both of them! The only alternatives to trying to make them compatible are
1) try to prove experimentally that Quantum Mechanics is actually wrong
2) try to prove experimentally that General Relativity is actually wrong
3) give up on the notion that mathematically describable "laws of physics" exist

If you are a theoretical physicist, as opposed to an experimental physicist or a philosopher, those alternatives are not really sensible.

GR and QM contradict on such major points as energy, with one saying that energy is everywhere and infinite and the other saying that Gravity is energy. Combining the two theories would yield infinite Gravity everywhere...which we don't see (nor could we, life couldn't exist).

The two theories are mutually exclusive. They could both be wrong or just one might be wrong, but both can't be correct...which makes String Theory's attempts to unite the two theories absurd.
