The increasing precision of Doppler Radial Velocity, photometry and spectroscopy of exoplanet atmospheres has dramatically altered our understanding of exoplanets and planetary systems. I will discuss how current advances in instrumentation and techniques, coupled with large-scale surveys, is poised to push the boundaries of exoplanet discovery and characterization with Doppler RVs . Using the Habitable Zone Planet Finder (HPF, for the 10m HET telescope) and NEID (for the 3.5m WIYN) as examples I shall highlight the observational, instrumental and astrophysical challenges in pushing to every higher differential velocity precision in the near infrared and the optical, where we stand as a field, and possible paths forward.
