And even for trivial questions, there is a lot out there that the doc developers ignored or hid.

For me, the current state of affairs is the difficulty of aiming search engines to the right answer. The answer might be out there, but figuring out HOW t oask the questions, which are the right keywords, etc - basically requires knowing where the answer is. LLMs have potential in rephrasing boththe question and what they might have glanced at here and there - even if obvious in hindsight.

Don’t use search engines unless you know what you’re searching. Which means I start with another material first (books, wiki, manual,…) which will give me enough ideas of what I want will be. Starting with a search engine is like searching for a piece of a jigzaw with only the picture on the box, you have to know it’s shape first and where it would go.

It's a very similar situation with concurrent programming. Knowing which instruction does a CAS, or the exact memory semantics of a particular load/store/etc., doesn't do much on its right own.
