This data is mostly used to test existing theory. Eventually we may find a discrepancy that suggests the Standard Model is missing something, though this seems unlikely in the near future as the model has accurately predicted pretty much everything we throw at it.

It's how science works best: you make your boat, then do everything in your power to sink it. The boats that stay afloat, like quantum chromodynamics, quantum field theory, and general relativity, are the ones that continue to work in ever-more difficult situations.
