Why do you think it seems unlikely? I've no idea if my usage of SO is typical, but I generally just ended up using it for pretty simple questions - the type that GPT is absolutely phenomenal at answering. The handful of complex, domain specific, questions I tried asking on SO still remain lingering even using their bounty system, or ended up being answered by myself.
Another nice thing is that SO is, ironically, often relatively hostile to asking questions. It seems like every post there's some group of people racing, often recklessly, to try to mark things as duplicates when they're not, asking for code samples even when the question clearly does not require it, etc. And then there's the passive aggressive stuff. It seems like 95% of the SO community is awesome, but that 5% sure is a turn-off from the site. GPT cuts through that layer of nonsense.
Most of SO’s traffic comes from organic search. While we don’t have data for SO traffic itself, we do know that search traffic is not declining.
While some users use ChatGPT to solve technical problems, it doesn’t seem likely that the search traffic they depend upon is an extreme outlier from search in general.
We do know that SO’s primary ad service is that of tech hiring, something that has cooled significantly in the last year.
