This is partly what I'm arguing against (along with the premature belief that we already have a good enough model). I don't see any reason why there would ever be a model that didn't look like our existing models (say in economics) but with more bells and whistles. I don't think there will every be the equivalent of quantum field theory in economics.

I'm basing this on having tried to find it myself, and becoming convinced that there is no such theory, and also that the rest of the field is correct in not trying to find such a theory.
