Absolutely. LLMs offer you compressed documentation at your fingertips. Instead of scrolling through man pages and function references to find that specific flag or parameter you are interested in for the problem at hand, you can directly formulate such a question to the LLM, and it will give you a pretty good result.
Another issue LLMs help with is identifying the correct keywords or terms to look up. Especially with manpages, I've had numerous times where I roughly know what I'm looking for, but in the presence of hundred-plus flags and options, I can't even grep to the right place because I don't know the exact term I need. So I sometimes use LLMs as glorified grep with semantic synonym support.
I think the GP was proposing an organic way to expand knowledge. Reading adjacent documentation expands your knowledge of what’s possible. An LLM will tell you how to do a specific thing, but you need to know such a thing is possible before you can effectively ask about it.
In this way, LLMs may passively discourage discovery by providing immediate, specific answers. Sometimes there is value in the journey.
