The discovery of the Higgs boson is a tremendous achievement for particle physics. However, because the Higgs boson cannot be naturally light, the absence of new physics in addition to the Higgs boson has sparked a crisis in particle theory. I review the reasons for this crisis, potential solutions and their experimental signatures. In particular, I focus the discussion on natural composite Higgs models which are sometimes overlooked in the literature. Finally, I briefly discuss the recent 750 GeV di-photon hint of new physics and what it could mean going forward.
