ChatGPT's rise linked to decline in public knowledge sharing on online Q&A platforms

A new study published in PNAS Nexus reveals that the widespread adoption of large language models (LLMs), such as ChatGPT, has led to a significant decline in public knowledge sharing on platforms like Stack Overflow. The study highlights a 25% reduction in user activity on the popular programming Q&A site within six months of ChatGPT’s release, relative to similar platforms where access to ChatGPT is restricted.
