Ask HN: How much of LLM coding skill comes from StackOverflow?

I would guess a lot as the best LLM coding answers I get often can be found on SO when I start searching for similar language.<p>But I have not been methodical about looking into it as &quot;when does this random token machine spit out useful results&quot; has been my focus far more than &quot;what are the actual texts it is pulling from&quot;
