While AI might have amplified the end, the drop-off preceded significant AI usage for coding.
So some possible reasons:
- Success: all the basic questions were answered, and the complex questions are hard to ask.
- Ownership: In its heyday, projects used SoF for their support channel because it meant they don't have to answer twice. Now projects prefer to isolate dependencies to github and not lose control over messaging to over-eager users.
- Incentives: Good SoF karma was a distinguishing feature in employment searches. Now it wouldn't make a difference, and is viewed as being too easy to scam
- Demand: Fewer new projects. We're past the days of Javascript and devops churn.
- Community: tight job markets make people less community-oriented
Some non-reasons:
- Competition (aside from AI at the end): SoF pretty much killed the competition in that niche (kind of like craigslist).
The volume of basic questions is unlimited. There are new technologies every year.

I think this is one major factor that is not getting enough consideration in this comment thread. By 2018-2020, it felt like the number of times that someone else had already asked the question had increased to the point that there was no reason to bother asking it. Google also continued to do a better and better job of surfacing the right StackOverflow thread, even if the SO search didn't.
In 2012 you might search Google, not find what you needed, go to StackOverflow, search and have no better luck, then make a post (and get flamed for it being a frequently-asked question but you were phrasing yours in a different / incorrect way and didn't find the "real" answer).
In 2017, you would search Google and the relevant StackOverflow thread would be in the top few results, so you wouldn't need to post and ask.
In 2020, Google's "rich snippets" were showing you the quick answers in the screen real estate that is now used by the AI Overview answers, and those often times had surfaced some info taken from StackOverflow.
And then, at the very end of 2022, ChatGPT came along and effectively acted as the StackOverflow search that you always wanted - you could phrase your question as poorly as you want, no one would flame you, and you'd get some semblance of the correct answer (at least for simple questions).
I think StackOverflow was ultimately a victim of it's own success. Most of the questions that would be asked by your normal "question asker" type of user were eventually "solved" and it was just a matter of how easy it was to find them. Google, ChatGPT, "AI Overviews", Claude Code, etc have simply made finding those long-answered questions much easier, as well as answering all of the "new" questions that could be posed - and without all of the drama and hassle of dealing with a human-moderated site.
