Applications for the third Complexity Global School (CGS) are now open. Like last year, the school will be hosted at Universidad de los Andes (Uniandes), in Bogotá, Colombia, but for the first time, applicants from all countries are eligible to apply. Roughly 60 students will be selected for the school, which will run July 28 – August 8, 2025. Supported by the Omidyar Network and the Ford Foundation, the school is free for all admitted students — tuition, room, board, and a travel stipend are included. Applications are due by March 2, 2025.

We examine how ChatGPT has changed the demand for freelancers in jobs where generative AI tools can act as substitutes or complements to human labor. Using BERTopic we partition job postings from a leading online freelancing platform into 116 fine-grained skill clusters and with GPT-4o we classify them as substitutable, complementary or unaffected by LLMs. Our analysis reveals that labor demand increased after the launch of ChatGPT, but only in skill clusters that were complementary to or unaffected by the AI tool. In contrast, demand for substitutable skills, such as writing and translation, decreased by 20–50% relative to the counterfactual trend, with the sharpest decline observed for short-term (1-3 week) jobs. Within complementary skill clusters, the results are mixed: demand for machine learning programming grew by 24%, and demand for AI-powered chatbot development nearly tripled, while demand for novice workers declined in general. This result suggests a shift toward more specialized expertise for freelancers rather than uniform growth across all complementary areas.

The Complex Systems Seminar Series covers a wide range of topics, providing an opportunity for presenters to share and attendees to become exposed to the latest research from different fields and disciplines. 

Agent-based simulation, artificial intelligence, artificial life, genetic algorithms, machine learning, neural networks, signal processing, social networks, system dynamics, and science itself are just a few of the many diverse topics that have been presented, all in an informal environment where questions and discussion are encouraged.

Robert Rosen was a leading theoretical biologist in the tradition of relational biology, making important contributions to the understanding of living systems.

We believe that Robert Rosen’s work represents valuable perspectives on biology, causality, and science as a whole, and that it deserves to be more widely known and read. Over the last four years, we have taken care in classifying his complete published works, including articles, chapters, commentaries, and books both in and out of print, and most importantly, scanning and sorting a small part of his vast collection of unedited notes, which contain ideas that extend beyond his published works.

Our hope is that interested readers will find a foundation here for a new science of biological systems, one that reflects the nature and complexity of these systems.
