Partially wrong but not all wrong!
Traditional physics do have limitations since in Quantum Mechanics nothing works as read in the books!! So everything is really relative to a scale in some ways!
But I do not personally believe that a Unified Theory of Everything is likely to exist! I do rather believe that we will have to settle to a Universal theory of unpredictability!
