I read and reread Matt arguments trying to understand his viewpoints. I think he got discouraged with the LHC non-null results in 2013.. and he wrote in separate page in August 2013 https://profmattstrassler.com/2013/08/27/a-first-stab-at-explaining-naturalness/ "This in turn is why so many particle physicists have long expected the LHC to discover more than just a single Higgs particle and nothing else… more than just the Standard Model’s one and only missing piece… and why it will be a profound discovery with far-reaching implications if, during the next five years or so, the LHC experts sweep the floor clean and find nothing more in the LHC’s data than the Higgs particle that was found in 2012." It's happening now.. it's 5 years from his pronouncement. Only Higgs and nothing else is "Profound discovery with far-reaching implications". There is possibility there may not even be a UV complete theory. To be on topic, where is Matt page about Vacuum Metastability? He should emphasize it too. Anyway. If AdS/CFT is UV complete. But it doesn't describe our spacetime. Is this duality just toy model or does it completely describe a hidden sector that can act as holographic surface. Is there any reference about this search for actual surface or it will remain as toy model for centuries to come? And can AdS/CFT explain the why of the vacuum metastability?
