“ A catastrophe is when a belief or certitude suddenly collapses. From its ruins, narrative, political, economic and ecological utopias can be reborn. ”

Can new narratives arise from ruins?
Raphaëlle Guidée is a specialist in narrative representations of economic, environmental and societal collapse. For over 10 years, she has analyzed the narratives surrounding Detroit’s bankruptcy in order to understand how an apparent ruin of capitalism can inspire discourses of domination or resistance. In La ville d’après : Détroit, une enquête narrative [The Aftermath City: Detroit, a narrative investigation] (Flammarion), rather than focusing on fictions, she seeks out testimonies and concrete stories, believing that modern times don’t need new narratives. We simply need alternative narratives. Read the transcription of the podcast.

Using AI to tell history
On February 10 and 11, France hosted the Summit for Action on Artificial Intelligence, bringing together international companies and heads of state to identify the potential and limits (notably environmental) of this tool. This is an opportunity for us to discuss the subject of generative AI with Raphaël Doan, a specialist in the sciences of Antiquity and author of the uchronia Si Rome n’avait pas chuté (If Rome hadn’t fallen), an essay imagining, with the help of AI, what might have happened if the Industrial Revolution had taken place under the Roman Empire. Through this experiment, fascinating possibilities for historical and archaeological research are outlined, as AI facilitates the processing of archives, the translation of lost languages and the deciphering of burnt texts.

Urban metabolism, at the heart of the matter
When we speak of urban metabolism, we are generally referring to the materials that enter and leave the city organism. Among these, waste plays a decisive role, challenging our understanding of what is clean and what is dirty, what is at the end of its life and what can be reused, what is new and what is outdated. Thus, studied from a qualitative rather than quantitative approach, waste reveals a great deal about our urban imaginations, which differ from country to country across the globe. This is what geographers Clément Dillenseger and Pierre Desvaux explain in Métabolisme(s). Matière en circulation, matière en transformation [Metabolism. Circulating matter, transformed matter] (co-authored with Laëtitia Mongeard, published by Éditions deux-cent-cinq). Read the podcast’s transcript.

Representing geological time
Noémie Goudal is a visual artist. Finalist for the 2024 Marcel Duchamp award, she works on our relationship with time, with a particular interest in paleoclimatology: the history of ancient climates. Basing her artistic work on the research carried out by contemporary scientists, she questions our relationship with the landscape and its movement, redefining our perception of the world.
