Since 2015, the global network of gravitational wave detectors has found ~50 black hole mergers and a couple of binary neutron star mergers, giving us a wealth of astrophysical information and a radically new way of looking at the cosmos. In this talk, I will describe what we can expect from this field over the next several years: quantum enhanced metrology, new detectors coming online in Japan and India, and the use of machine learning to extend the frequency band of the detectors to search for 'forbidden' black holes of unusually small (or large) size. The multi detector network should give dramatic improvements in the ability to localize events in the sky and to use gravitational waves to build a universal distance ladder.
