What have we learned from the discovery of the Higgs boson?

The discovery of the Higgs boson has been the most spectacular scientific event of 2012. But how did this discovery affect our understanding of the physical laws governing the universe? I will review the implications of the experimental results for the theory of electroweak interactions and for cosmology. I will also discuss the main issues that are still left unresolved and how we will be able to address them with future experiments.
