Call it a conspiracy, but I'm still convinced that #StackOverflow is dying primarily because the marketing for CodeGen AI demotivated a lot of people to the point that they do not even want to program anything anymore.
I've seen a lot of (what could have been) Juniors avoid doing anything with code because AI will be able to do it in 5 years anyway so there is no point in learning it.
And then the large layoffs, so the remaining ones are probably too busy to write answers there
