Quasiparticles vs elementary particles

Quasiparticle
As a phisicist once amazingly put it in a talk Ciro watched:
It all depends on how much energy you have to probe nature with. Previously, we thought protons were elementary particles. But then we used more energy and found that they aren't.
If some alien race had even less energy, they might not know about electrons at all, and could think that anyons are actually elementary.
Being an "elementary particle" is always a possibly temporary label.
