Directional detection of low-energy nuclear and electronic recoils is broadly desirable in nuclear and particle physics. Applications include coherent elastic neutrino-nucleus scattering (CEνNS), astrophysical neutrino measurements, probing dark matter (DM) beneath the neutrino fog, and possibly confirming the galactic origin of a DM signal. While gaseous Time Projection Chambers (TPCs) offer the required gain and readout granularity, they must be very large to achieve the required sensitivity for several of these physics applications. We discuss several aspects of future directional recoil detection experiments such as background rejection, detector scalability, directional performance on electron recoils, and improving directional performance with deep neural networks. Finally, we discuss the construction of CYGNUS HD 40, our latest prototype detector, intended to pave the way for cost-effective, large directional detectors.
