I think I could qualify as an expert on various topics relative to many average people. But it always bothered me when experts wanted to "just be believed". In your example, it doesn't long to explain why a database is better than the file system in this instance and a moderately intelligent should be able to understand and not need you or Claude as the source of truth.

So I think it can be good people are able to "AI" to question expert opinions - though naturally, as you say, it's bad if people take the AI as a single authority akin to an expert.
