They're easy to recall, but you have to know what to recall in the first place. Or even know enough of the territory to realise there's something to recall. Without enough background, you'll get a whole set of amazing tools that you have no idea what to do with.
For example, you may be able to write a long description of your problem with some ideas how to steer the AI to give you possible solutions. And the AI may figure out what the problem is and that the hyperloglog is something that could be useful to you. And you may have the awesome programming skills to implement that. But that's a lot of maybes. It would be much faster/easier if you knew about hyperloglog ahead of time and just asked for the implementation or library recommendation.
Or even if you don't know about the actual solution, you'd have enough of CS vocabulary to ask: "how do I get a fast, approximate distinct count from a multiset". It would take a long imprecise description to get the same thing for a coder with no theory background.
