Slowly and bit by bit AI services are taking StackOverflow over. It's okay as a product, the usual LLM without much attribution plus a bit of handpicked content from the past. But it's also pushing the human interactions on this site to the side, more and more and more. This will decrease, not increase new questions and even more so new answers, unfortunately.
I want my contributions to be seen and read by other humans. I don't want my contributions to be used by a machine and maybe a little bit of attribution given somewhere. I especially don't want the AI service to be placed right on the site where I might contribute content, right above that content. At least I don't want to contribute for free to such an arrangement.
StackOverflow missed the chance in the last couple of years to be a strong voice for user generated content from users for users. Instead it looks increasingly like any LLM service, with a preference for a single data source and with a database of questions from the past. I wish more energy would have been invested in making asking and answering easier, like duplicate detection, question improvements, .. The AI generated content service has the top spot now.
To also give some specific feedback: I tried to search for the stopwatch function in Julia, i.e. this question with the same title. My input was: "How to implement a stopwatch function in Julia?". It didn't find anything and produced an AI generated answer without any attribution.
And it's still quite slow I would say. Something common like "How to format a string in Python?" takes 12s to start printing and 25s to finish (and links to a zero scored, rather unhelpful answer). Other LLM services need 2s, search engines <1s.
