The former expectation does not seem very realistic. Albeit anecdotally, in my experience, most people I’ve surveyed over the years (many of them very intelligent and well educated individuals) have little or no familiarity with David Hume, let alone with any particular argument he championed. Even among those who took an introductory philosophy course back in junior college, few seem to remember much of anything about Hume.
The latter expectation, or rather hope, strikes me as rather devious and scheming. The problem of induction neatly lends itself as a ready gateway to a god-of-the-gaps style apologetic.
