Is the theory of everything really such a big deal? For decades, every physicist in the world has said so. But are they correct?
If the standard model is valid to almost the Planck energy, then there is nothing to be discovered any more. Maybe the only point remaining is the explanation of the standard model parameters.
If that is all, the TOE is not a holy grail, it is a paper cup. After all, who cares about solving mysteries? People want new mysteries, not solutions to old ones. People want drama, not peacefulness. People want to think that a TOE is like reading the mind of god, they do not want to think that a TOE is just reading formulas.
