The discussion centers on the lack of detection of supersymmetric (SUSY) particles at the LHC and its implications for theorists and funding. The absence of evidence raises questions about the viability of SUSY, especially as it relates to dark matter candidates and gauge unification. While some argue that the LHC has only explored a small fraction of the parameter space for SUSY, others contend that the most promising regions have not yielded results, suggesting a higher energy scale for SUSY phenomena. Additionally, challenges such as neutrinoless double beta decay and discrepancies in muon g-2 measurements further complicate the SUSY narrative. Overall, the absence of SUSY particles at the LHC poses significant challenges for the theory's future relevance and funding prospects.

From what I gather, the "universality" of the three varieties of leptons is the real problem here. They are lumped together as a single type of entity when they each have their own composition and therefore variances in the mass each type starts out with. To expect them to all decay similarly seems quite curious. You can fire three bullets of different masses from the same rifle but you certainly would not expect all three to land at exactly the same location downrange. The "violations" would seem to be inherent due to the false assumption that they were all the same in the beginning.

That doesn't make any sense.
