I don't disagree, but that does not change the fact that people have moved from sites like SO to Discord for this purpose.
There are Q&A channels, so not everything is chat, but Discord search is abysmal
Slack is another place where former SO content / answers are happening. Discourse too. The tl;dr is that it has become more fragmented, for better or worse
SO has a related problem to Reddit. Some mods high on their status and power
