How is holography any more concrete than string theory? It is just as untestable.

You use it as a tool to compute what happens in real things, such as quark-gluon plasma or certain condensed matter systems.

You should be careful to not overstate it's rigorous application to QGP or condensed matter systems though.

For example, for QGP, holography can paint a nice picture, but we don't know a holographic dual for Nc=3 QCD.

We must not be discussing the same thing.

EDIT: yup, I am not knowledgable enough to be in this conversation.
