Future high energy colliders are essential to unravel the mysteries of the universe. The question is how best to access higher energies. After decades of physically larger and larger pp and e+e- machines, a compact and power-efficient muon collider would represent a paradigm shift for the field. In this talk, I'll make the case that a multi-TeV Muon Collider is a compelling successor to the LHC, and outline recent progress in overcoming technical challenges. In particular, I'll discuss how the unique collision environment influences detector design, and demonstrate that we can extract high quality physics with existing and emerging technologies.
