Yes, that is the major problem with LLMs in general. There is no solution aside from "train on another different source (like Reddit)", but then we rinse & repeat.

I am worried, because there are increasing cases where open source docs are going offline because they can't take the bandwidth costs of the big LLM bots recrawling hundreds of times per day. Wikipedia is also getting hammered. There is so much waste and diminishing returns

You can’t exactly feed it a manual and expect it to extrapolate or understand (for that matter “what manual).

You can do that to a degree (RLVR). They are also paying human experts. But that's the situation now. Who knows how it will be in a couple more years. Maybe training AIs will be like writing a library, framework, ...

From the questions people ask and from online accounts.
