It depends on what you are interested in. What it really means is that it provides an approximation-free prescription for extracting observables from the QCD action. Given some experimentally-measured observables (the pion mass, the kaon mass, etc. as long as you include 1 observable per parameter in QCD, meaning 1 gauge coupling + 1 per quark flavor you include in your simulation) you can calculate all other quantities---in a world that is pure QCD. We are now getting to an era where we can do lattice QCD+QED, but we cannot do…</p><p><a href="https://hackerpaper.kaipfister.de/p/0906.3599/">Paper and discussion history</a>.
