I think needing multiple searches and sources is a good thing, personally. Yes it takes more time and effort but it reinforces research skills. Performing the search yourself provides an opportunity to critically evaluate the information you’re finding and, if applicable, take into account any bias a source may have.
Can’t comment on code generation.
I suppose it depends on the Linux difficulty but reading through documentation and ArchWiki typically gets me enough info to make a more informed/refined search. You’re also likely to stumble across information you’ll want to know rather than just find an answer to the question you’re asking.

No, my responses are literally “AI answers, legwork teaches.” If you don’t understand or appreciate that difference you are doing yourself a disservice.
