This is especially tough because of how much skill it takes for you the questioner to not make the other person feel stupid when they realize they can't answer your questions.
Yeah, I think the other thing that's made me shy away from it more as I've gotten older is asking the "stupid" question, getting a jargon-laden response, and realizing: this person isn't equipped to communicate the concept. It can be pretty exhausting to be the questioner in that case.
