Generative AI Drives 76% Drop in Stack Overflow Questions, Pushing Experts Out

Summary
University of Auckland research says generative AI is accelerating the exit of Stack Overflow’s highest-skill contributors, as experts see less reward in sharing knowledge that chatbots now deliver instantly.
Nearly 76% fewer monthly questions have been posted since ChatGPT’s 2022 arrival, reflecting both shrinking user demand and a loss of answerers that the study says may be hard to replace.
Stack Overflow’s own problems also fed the decline: users cited heavy-handed moderation and a self-righteous culture, while AI became a faster tool for routine coding and syntax queries.
Dr. Kenny Ching calls the effect “signal compression” — AI makes expert and non-expert answers harder to distinguish, weakening incentives for specialists to contribute.
Researchers warn the pattern could spread beyond coding forums into classrooms, offices and scientific communities, raising questions about where future AI systems will find high-quality training data.
