With lack of new physics discoveries the focus has shifted to precision measurements to search for faint hints of new physics signatures. With vasts amount of high quality data to be collected at the High-Luminosity phase of the LHC, and future collider proposals such as FCCee, precision measurements have become all the more central as primary tools for discovering new physics. However, interpretation of precision collider measurements requires us to have already measured the Standard Model parameters such as coupling constants and particle masses to a high degree of precision. Measurements impacted by strong interactions such as the strong coupling constant and the top quark mass remain bottlenecks in this program. In this talk I will discuss broadly the problem of modeling hadronization effects that must be overcome for a successful collider physics program as modeling brings new conceptual uncertainties that cannot be precisely quantified. I will describe recent progress in overcoming this problem in the context of jet substructure methods for strong coupling and top quark masses, such as using energy correlators, and sketch the way forward.
