There hasn't been a total lack of progress by any means.

Unfortunately, "confirming the standard model again in some new way", while good science, also does nothing to get particle physics out of its rut.

I originally wrote "useful" science when I first wrote that sentence, but... it's debatable how useful it is, actually. People have been taught that measuring the utility of science is heresy, but I find that insane. It is completely possible to have science that isn't that useful, even to other science, let alone to any other purpose. Confirming the standard model yet harder isn't really useful. Of course, you have to run the experiments to confirm the standard model, in the hopes that maybe it won't, I'm saying the result of confirming the standard model is of debatable utility.
