You are contradicting yourself here: "spending billions on another collider in an attempt to essentially validate SUSY is irresponsible. A few years ago, a bunch of physical philosophers tried to justify this turn of particle physics in general away from experiment" The proposed collider is an experiment. It might incidentally find support for SUSY (unlikely) but its purpose would be to produce precision data about high energy physics, whatever that physics is. As others have noted, the Engadget article is also misleading, since what has been approved is not a collider, just a design study.

Not quite. The experiment has already been done, it was called the LHC. It found no evidence for SUSY, but instead of re-evaluating SUSY since it's needed for all modern particle phenomology as well as many unification theories, the argument is to "keep looking." Fine, keep looking, if you want, but it certainly won't be with a larger collider, especially since the last search failed. That failure demands a re-assessment of resource allocation. Finally, another comment said the LHC was to study the higgs. I'm not sure about that since the higgs was already found before, it just wasn't at the significance level particle physicists like. Most of the people I talked who worked on the LHC told me the main thing behind the LHC was to see SUSY or general new physics beyond the SM.

    The Tevatron indeed saw something at the right mass, just after the first hints from LHC came in: https://news.fnal.gov/2012/03/tevatron-experiments-report-latest-results-search-higgs-boson/ https://news.fnal.gov/2012/03/tevatron-experiments-report-la... It's unclear to me if it could have ever pushed this to enough sigmas to claim discovery.

  You are fixating on SUSY, not CERN. A new collider is needed to find out what's beyond the Standard Model, whether it's SUSY or something else entirely. Your statement that "it certainly won't be with a larger collider, especially since the last search failed" frankly makes no sense, and the claim that "the higgs was already found before" is incorrect. This is mostly true though: "the main thing behind the LHC was to see SUSY or general new physics beyond the SM" (I say "mostly" because the energy range was chosen to ensure that either the Higgs or something else would be found; if it existed, it had to be in that range, and if not, something else had to do its job). And that statement remains true about the next collider. It will look for "SUSY or general new physics beyond the SM".
