In particle physics, all fermions in the standard model, except possibly neutrinos, are Dirac fermions.

In condensed matter physics, low-energy excitations[clarification needed] in graphene and topological insulators, among others, are fermionic quasiparticles described by a pseudo-relativistic Dirac equation.

What is a Dirac fermion?
Don’t get me wrong, this sort of fundamental research is well worth doing, but the link to practical technology is handwaving. Physicists should not be asked to pretend that all knowledge has to be useful.
