Artificial intelligence makes every individual's work better while simultaneously making the entire world's collection of ideas more boring and redundant.
Generative models prioritize the most probable and high-quality outputs, leading millions of people toward the same creative peaks. While each person might feel like they are producing a superior product, the total pool of ideas shrinks as it crowds around a single optimal style. We usually think of better tools as a way to expand our creative horizons. Instead, this trend suggests we are trading unique human variety for a polished, homogenized culture. It creates a future where everything is high quality but nothing is genuinely different.
Ex Ante Evaluation of AI-Induced Idea Diversity Collapse
arXiv · 2605.06540
Creative AI systems are typically evaluated at the level of individual utility, yet creative outputs are consumed in populations: an idea loses value when many others produce similar ones. This creates an evaluation blind spot, as AI can improve individual outputs while increasing population-level crowding. We introduce a human-relative framework for benchmarking AI-induced human diversity collapse without requiring human-AI interaction data, providing an ex ante protocol to estimate crowding ri
