AdS/CFT correspondence is a pretty old idea, whether it will yield something useful is still to be seen. Our world is not an N=4 Yangs Mills CFT, and our space is not AdS, so both sides of the correspondence are basically toy models that have been known for a while and haven't produced verifiable predictions (other than supersymmetric partners we haven't seen).

They're toy models, albeit rather sophisticated ones. Their utility is that they can give us concrete demonstrations of various conjectures about gravity, holography, and gauge theories.

Sure, but there is significant concern about how meaningful those demonstrations are since the theories that are most similar to the toy examples are themselves probably dead ends.
