Nothing. We are centuries away from using anything in HEP in tech application. (If someone thinks otherwise I'd love to hear counterpoints!) The thing is, subatomic stuff is extremely energy dense and packed very stably into particles and atoms. Even to just crack open that package we require massive machines like the LHC. Even if we could control things there it's not clear that it's even possible to rearrange the parts into other configurations. All such configurations would be extremely energy dense and intrinsically unstable, with QM making sure they decay quickly. So figuring out what stuff is made of doesn't give us more ways to interact with it. The good news is that we're far from done understanding how atoms can combine into interesting structures. Like _really_ far from done. From topological states of matter to meta materials there are lots of surprises.
