I agree that being open to novelty in encountering strangers and new art have something akin to each other. There really are two types of people in this regard: those that welcome and those that eschew new experiences.
Being overly conservative and closed to the new would leave us closed to developing and to becoming stale and stagnant. It's good to be discerning, not totally open to every novelty and able to see what's worthy from what's not but to be at least open to being exposed to new developments and ideas.
