(Disclaimer: I've been on SO since 2009 with almost 200k rep now)

Yes, SO has rightfully earned a reputation for being unfriendly (at best!) to software-dev neophytes; I don't want to handwave-away the problem, but I don't believe SO was intended as a good place for beginners, nor as a place tolerant of _forum faux-pas_[1]; SO was just intended as a better (and free) replacement for expertsexchange - and the disconnected, disparate collection of web-forums or Usenet groups that focused on a single language or platform.

So if I wrote the above post, I think I'd re-phrase it by saying SO was an example of "good _professional_ interaction": the site/format works great when everyone understands each other. SO would be even better if it could solve that problem, but to-date, no-one has figured-out a solution to that problem; whereas if we look at ChatGPT-as-a-replacement-for-SO, it hasn't solved the problem either, but avoids it, by not having people interact with other people anymore - this may or may not be a good thing in the long term.
