**7. Discussion**

Throughout this paper we reviewed several research contributions over the last few years showcasing the immediate applicability of modelling and simulation methods expanded from statistical physics and network theory to various aspects of economics, finance and everyday life. From the big picture is system-level appreciation of the interdependence and nontrivial relations that are present in our most fundamental infrastructure, through fine-grained, local models of interaction that mirror high frequency trading asset behaviour to estimation of local and global economic behaviour in normal and highly anomalous times. These, and many other contributions, give us both new perspectives on known phenomena and mitigation tools in order to manage them such that they do not lead to massive damage. Even with this wide range of topics covered and approaches demonstrated, this is but a grain in the wide landscape of research conducted over the past decades, and evolving still, bridging the gap between methods and discoveries from physics to social and economic life.

Our economy, a textbook case of complex, adaptive system, is comprised of multiple time scales, types of interactions and agents driven by fear, greed, hope and desire, aiming to improve their state compared to themselves and others, poses a grea<sup>t</sup> challenge not typically encountered in physics, where particles' knowledge of governing rules does not change their behaviour. Yet, many patterns emerge over time that show that, nonetheless, there are regularities and laws governing some of the observable outcomes. There are arguably many more open questions, from big to small, ye<sup>t</sup> to be answered pertaining to everyday life in its various aspects (economics, epidemiology, mobility, transportation and many more) compared to"classical" physics, and the growing body of research is a strong corroboration of that. The development of network science, econophysics and sociophysics has laid the directions, but the journey is far from over.
