When people talk about the Theory of Everything, they usually think of the theories that are trying to unify GR and QM (such as SMT and LQG), since this is what the majority of Theoretical Physicists are working toward, unification. However, I've just begun reading Smolin's Three Roads to Quantum Gravity, and have been wondering: What do you all think about replacing General Relativity and Quantum Mechanics with theories that are more compatible?
When I first heard that there were actually people working towards this, I thought they must just be some crackpots who were trying to be unique...but now I realize that there are actually quite a few very good scientists working on this problem.
So, what do you think? Can GR and QM be replaced with better theories? Could that turn out to be the Theory of Everything? Also, exactly what theories/hypotheses do you know of that have been put forward as possible replacements?
Any response is appreciated.
