This has been my experience.

My initial (most popular) questions (and I asked almost twice as many questions, as I gave answers) were pretty basic, but they started getting a lot more difficult, as time went on, and they became unanswered, almost always (I often ended up answering my own question, after I figured it out on my own).

I was pretty pissed at this, because the things I encountered, were the types of things that people who ship, encounter; not academic exercises.

Tells me that, for all the bluster, a lot of folks on there, don't ship.

LLMs may sometimes give pretty sloppy answers, but they are almost always ship-relevant.
