Large language models (LLMs) like ChatGPT are affecting online knowledge repositories such as Stack Overflow, leading to a 25% decrease in activity. This decline is not limited to low-quality content and affects posts by users of all experience levels. The impact is greater on posts related to popular programming languages.

The transformation of open data into privately-owned content may have implications for competition in the AI sector and consumer welfare. The study raises concerns about the future of the open web and the sharing of information online.
