A 5 to 10 day jaunt to other major cities or developed countries that you spend in a Hilton/Marriot/Hyatt, ride in Uber/Lyfts, and take selfies to put on instagram/snapchat all the while not speaking to anyone outside of the staff you communicate with at the hotel/restaurant is not exposing one's self to different views/culture/people.

And I think that's what the original commenter was alluding to.
