The scattering of electroweak bosons at TeV-scale super colliders is a powerful mechanism that probes spin and charge configurations inaccessible to quark and gluon scattering. Electroweak vector boson scattering (VBS) processes therefore give unique insights into the Standard Model's gauge and Higgs sectors, as well as into models of new physics. In this talk, we review experimental results and theoretical developments of VBS at the Large Hadron Collider, its high luminosity upgrade, and its potential successors.
