    If string theory is proven correct, then quantum field theory should be deduced from it where quantum theory holds.

    quantum field theory is always a limit of string theory*. for example, you can deduce things like scattering amplitudes of gluons and gravitons from string theory.

    *probably too strong of a statement, it might be possible for some qft's to not be generalizable to string theory (in a non trivial way at least)
