A sad trend in physics:
Most of the talk was about the hierarchy problem and “naturalness”, with the forward-looking conclusion the same one that Seiberg’s colleague Arkani-Hamed has been aggressively pushing: the main significance of LHC results will be telling us that the world is either “natural” (likely by discovering SUSY) or “unnatural” (in which case there’s a multiverse and it’s hopeless to even try to predict SM parameters). Given the negative results about SUSY so far, this conclusion pretty much means that the students at the IAS are being told that the LHC results mean it’s the multiverse, and they shouldn’t even think about trying to figure out where the SM comes from since that’s a lost cause.
