In this talk I give a brief assessment of the “AdS/QCD correspondence,” its successes, and its failures. I begin with a review of the AdS/CFT correspondence, with an emphasis on why the large N, large ’t Hooft coupling limit is necessary for a calculable theory. I then briefly discuss attempts to extrapolate this correspondence to QCD‐like theories, stressing why the failure of the large ’t Hooft coupling limit is more important than the breakdown of the large N expansion. I sketch how event shapes can manifest stringy physics, and close with some brief remarks on the prospects for future improvements.
