%X Cosmology presents the best hope of measuring the sum of neutrino masses in the future. The Cosmic Microwave Background (CMB) has already been a treasure trove of information; from Planck, BICEP/KECK, and their predecessors; and will continue to provide ever more precise information with upcoming or proposed CMB experiments, such as LiteBird, CMB-S4, CORE and PICO. These missions will have great synergy with other branches of cosmology. In particular, massive neutrinos leave a distinct imprint on the matter distribution of the universe, which upcoming large-scale structure experiments such as Euclid and the Square Kilometre Array will observe with unprecedented levels of precision. The uncertainty in modelling of non-linear structure formation is often neglected in other forecasts, or scales corresponding to this regime are entirely removed. In this work, we take into account that our understanding of non-linear modelling is imperfect. We show that a neutrino mass sum measurement is all but guaranteed from cosmology in the next decade and that this statement is robust to choice of cosmological model or modelling of non-linear effects.
