Nearly 30 years ago I wrote a piece for Sociological Research Online entitled: ‘Simulation - A Way Forward?’ One thing I will do in the closing plenary is reflect on how what I have heard and seen informs an answer to that question today, but here are some things to note which whilst I do believe in the great potential value of simulation as a tool of social science still at this point remain issues for me given that like Paul Cilliers I believe that modelling complex systems is impossible but nevertheless we have to model them: getting beyond a micro-emergent account; developing an understanding of the role of social structures which gives them causal powers; enabling an account of how power works in relation to the capacity of agents to shape social structures; writing nature and its power into our simulations.
Artificial intelligence is undergoing a profound transformation. For much of its history, AI systems functioned primarily as analytical models: they classified images, predicted outcomes, or detected patterns in data. Today, however, a new generation of systems is emerging. AI agents built on large language models can plan tasks, access tools, interact with data environments, and coordinate actions across digital systems.
In this shift, AI is moving from model to actor.
This transformation has far-reaching implications. As AI systems begin to act autonomously in digital infrastructures—interacting with humans, organizations, and other agents—they become embedded in complex social systems rather than merely analysing them.
Recent developments in AI agent architectures illustrate this transition. By combining large language models with memory, planning mechanisms, and tool access, AI agents are able to pursue goals, interact with data sources, and execute sequences of actions across digital environments. These capabilities blur the traditional boundary between analytical models and operational decision systems.
Rather than viewing AI purely as a technological capability, we may need to understand it as a new class of actors embedded in socio-technical systems. This perspective opens a new research frontier for computational social science: studying and shaping societies in which human and artificial agents increasingly interact, collaborate, and co-evolve.
From this perspective, the challenge is no longer only to evaluate models, but to understand and govern agent behaviour, interactions, and decision environments. As organizations begin to deploy AI agents within workflows, platforms, and information infrastructures, questions of transparency, accountability, and coordination become central.
The talk argues that computational social science—and particularly traditions such as agent-based modelling—offers valuable conceptual tools for analysing this emerging landscape. Concepts such as interaction rules, bounded rationality, emergence, and multi-agent dynamics may become essential for understanding the behaviour of AI agents operating within complex social systems.
Community-engaged systems science offers powerful tools for tackling complex public health problems — particularly when co-produced with the communities and stakeholders who are both actors in, and impacted by, the system. This talk illustrates this approach through two examples. First, a partnership with Los Angeles County government to build smart tools and analytics for community food systems, using participatory group model building and systems modeling to address food insecurity and guide local food policy. Second is the development of systems and agent-based models within a large precision nutrition consortium, to map ecological factors across individual, household, community, and structural levels shaping equitable uptake of personalized nutrition, and identify leverage points for population-level interventions.
