Except we know, and the founders of quantum mechanics also realized, that the properties of the matter we care about and interact with is driven by the properties of electrons and atoms. That analogy has broken down. It’s not to say that we couldn’t learn something at 100TeV that could be useful or even revolutionary like QM was, but we also don’t really have any reason to believe that right now other than cheery optimism. I’m all for finding high energy physics, I just don’t think it can justify it’s current budget in the quest for newer bigger colliders at higher and higher energies.
