Maybe StackOverflow is dying because its community is full of incredibly toxic, passive-aggressive and hostile basement dwellers who will berate, downvote and lock the threads of anybody who dares ask a programming question. Genuinely the kind of people you often see moderating subreddits or Discord servers who have never been punched in the face.
ChatGPT hammered the final nail in the site's coffin because it's now become a tool where you can ask specific programming questions and likely get an answer that isn't "use the search bar you fucking dipshit. Question closed as off-topic."
