Helpfully, neither is "I won't solve it nor help anyone with it" actually normal. That's what documentation, mentorship, peer review and coaching is for. Someone has to actually write all that stuff. If I solved it initially, that someone is me. Now it's got my name on it (right there in the docs, as the author) and anyone else can tap on my shoulder. I'm happy to clarify (and improve that documentation) if something is unclear.

Here, of course, is finally where AI can plausibly enter the picture. It's pretty good at search! So if someone has learned, and understood, and written it down, that documentation can be consumed, surfaced, and learned by a new hire. But if the new hire doesn't actually learn from that, then they can't improve it with their own understanding. That's the danger.
