The traffic picture is stark: public questions on Stack Overflow have moved from mass participation to a thin monthly stream.

OpenAI released ChatGPT in late November 2022. At that point, Stack Overflow was still receiving roughly 100,000 questions per month. One year later, by October 2023, monthly question volume had fallen 50%. During that same year, a broad set of AI chat assistants also entered developer workflows.
As AI-powered coding agents became more common, developers could hand a requirement to a system that would propose architecture, generate code, debug failures, and suggest fixes. That workflow lowers the need to visit Stack Overflow for a public answer or to search for an existing community thread.
Stack Overflow has accumulated many years of searchable public questions, edits, and solution paths. The rise of private AI conversations changes how new troubleshooting experience is shared: a problem may be solved inside a chat session, but the result does not necessarily appear online for other developers to find, challenge, or improve. For fast-moving programming languages, frameworks, and toolchains, a steady inflow of new questions and public answers still matters.
