Classical Mechanics (CM) or Quantum Mechanics (QM) is technically wrong. That doesn't mean they are irrelevant or have less significance, but they are wrong regardless of how accurate they are. Can we also say the same thing about Quantum Field Theory (QFT) or General Theory of Relativity (GR) because they are not The Theory of Everything (ToE)?
Or should we use the term 'correct but incomplete' for QFT and GR and 'accurate but wrong' for CM and QM?
Update: I see some confusion in the comments and answers due to the ill-posed nature of my question. Let me be more specific. As @Causative pointed out, I agree that CM is more wrong than QFT/GR. But I am hesitating to accept that the same can be said of QFT with respect to the ultimate ToE. Because to my best knowledge, we can apply CM to any particle but the position it predicts would be slightly off from the actual position. This slight inaccuracy gets bigger when the particle is of very high speed or of microscopic scale. This I don't think is the case with QFT. In QFT, we cannot apply this theory to let's say describe the interaction between galaxies. We need GR for that. However, using GR we cannot describe the interaction between 'point particles'. It's not the case that we can and it gives inaccurate results. We cannot apply. So, to me probably the problem with QFT and GR is that they are successful in their own domain but we don't have a unified theory. If we can unify them, we will have the ToE. However, if I am wrong in my premise, then it seems that even after we successfully uinify GR and QFT, the ToE will still be inaccurate.
