I recently came across a startling piece of data — the traffic to Stack Overflow, the world's largest programmer Q&A community, has accelerated its decline significantly since the launch of ChatGPT at the end of 2022. This knowledge-sharing platform, founded in 1998, was once a must-visit site for generations of developers, but now faces direct impact from AI tools.

Think about it, in the past, solving technical problems required browsing through dozens of posts, but now a single prompt can provide a code solution — this shift in convenience poses a clear threat to traditional Q&A platforms. Not only Stack Overflow, but many communities relying on user-generated content are undergoing this transformation. This reflects how AI tools are changing the entire ecosystem of knowledge acquisition and sharing.
