Modelling the emergence of open-ended technological evolution (2508.04828v1)

Abstract: Humans stand alone in terms of their potential to collectively and cumulatively improve technologies in an open-ended manner. This open-endedness provides societies with the ability to continually expand their resources and to increase their capacity to store, transmit and process information at a collective-level. Here, we propose that the production of resources arises from the interaction between technological systems (a society's repertoire of interdependent skills, techniques and artifacts) and search spaces (the aggregate collection of needs, problems and goals within a society). Starting from this premise we develop a macro-level model wherein both technological systems and search spaces are subject to cultural evolutionary dynamics. By manipulating the extent to which these dynamics are characterised by stochastic or selection-like processes, we demonstrate that open-ended growth is extremely rare, historically contingent and only possible when technological systems and search spaces co-evolve. Here, stochastic factors must be strong enough to continually perturb the dynamics into a far-from-equilibrium state, whereas selection-like factors help maintain effectiveness and ensure the sustained production of resources. Only when this co-evolutionary dynamic maintains effective technological systems, supports the ongoing expansion of the search space and leads to an increased provision of resources do we observe open-ended technological evolution.
