AI-generated posters are becoming more common in public spaces, sparking concerns among visual artists and critics about their impact on aesthetics and cultural quality. In cities like Strasbourg and Rouen in France, local authorities and event organizers have started using AI-created visuals, often at the expense of traditional artistic practices. This trend has drawn attention on the subreddit IaCaca, which was created in December 2025 and has grown to over 124,000 members. The community discusses the increasing presence of AI in visual design, often criticizing it for lacking originality and creativity. In Strasbourg, illustrator Clémence Dupont has noticed a rise in the use of AI-generated visuals by small businesses, cultural events, and even local government. These posters are frequently criticized for their uniformity and lack of creativity, with Dupont describing them as sterile and devoid of soul. She has also raised concerns about clients using AI to generate initial design concepts, sometimes even using her own artwork without permission. This practice, she argues, undermines the value of human-created art and dispossesses artists of their work. In Strasbourg, the city's carnival poster, which was revealed to be AI-generated, sparked controversy among local illustrators. The poster was among three options submitted by the agency Welcome Byzance, and the city chose one of the AI-generated designs due to budget constraints. This decision led to discussions about how cultural funding is allocated and the value placed on human-created art. The incident highlighted the tension between cost efficiency and artistic integrity in public projects. In Rouen, the use of AI-generated visuals for a poster titled Rouen frosted and a Christmas sweater contest video prompted a response from artists and authors. The collective Autrices & Auteurs Rouen pointed out the ethical and political implications of AI-generated content, noting that these visuals often lack coherence and overwhelm the viewer with excessive information. They argue that the reliance on AI in visual communication raises questions about the authenticity and depth of the content being produced. Professor Alberto Romele from the Sorbonne explains that the aesthetic of AI-generated images is shaped by the data they are trained on, such as image banks like Shutterstock or Getty Images. This often results in a "smoothing" effect, producing generic and unoriginal visuals. He also highlights the copyright issues surrounding AI, as these models are trained on millions of images without the consent of the original creators. While AI-generated visuals may be more accessible and cost-effective for the general public, critics argue that this trend risks impoverishing culture. AI-generated images often fail to reflect the latest scientific discoveries and can instead produce misleading or sensational content. In response, some local authorities are beginning to reconsider their use of AI-generated visuals. In Rouen, the city is preparing an internal charter to exclude generative AI from its visuals, while in Strasbourg, discussions are ongoing about adopting more favorable practices for creators. The long-term impact of these incidents on public perception and policy remains to be seen, but the growing awareness and mobilization of artists and critics suggest a potential shift in how AI-generated content is viewed and used in public spaces.
