Those aren't super rare these days, I don't know why arbitrary credentials would matter for this purpose, but incidentally, the notion that they would matter in conversation at all kind of speaks to the type of engagement you might be having with them, which may indeed be different than what I care about.

Personally I don't find people all that engaging the more inclined they are to go looking up answers, to me it represents a certain amount of discomfort with uncertainty, ego, that are necessary for a fun conversation. If someone has an answer because of their experience, great, otherwise it's ok to not know in the moment and continue on.

In one case, I had a friendship kind of fizzle out because we'd be hanging and I'd express some curiosity that I'd hope he'd build on with his own experience or his own sense of wonder, but because he only cared about authoritative facts, he'd google the answer and get frustrated that I only cared about his opinion on what the answer might be. The actual fact was incidental, and this conflict regularly led to impasse where I'd clarify I don't care what the internet says etc.. and I'm fine with that because he wasn't really interested in thought exercises.

A concrete hypothetical mundane example might be posing "How do you think the Iran war might impact gas prices here?" and they'd just look up the history and trends, and then kind of stop there. Dull, I want a human response, speculate and build on it, let yourself be wrong.
