building another collider is very silly imo. super cern would make sense if the ship hadn't so thoroughly sailed on supersymmetry, but it sort of has, so it's hard to see why such an undertaking would be worthwhile. The LHC has done a lot for less fundamental physics, but in terms of the Higgs, that's kind of the only huge thing that the LHC has discovered. and the higgs is important, but not nearly as important as people make it out to be. the higgs field gives rise to the bare masses of particles, but most of the mass in the universe is actually held in the binding energy of quarks and gluons.
I worked on some SUSY models last decade and the LHC limits were a pretty big blow to everyone's motivation, mine included. Maybe we find something at the next energy frontier, but there's not a compelling reason to go there yet. One could say that it would be good to measure Higgs parameters, but we could also do that with an electron collider at the Higgs resonance for likely a lower cost. It's a mess
who need they SUSSY ate
