Lately my wife I have been using Apple’s Find My Friends app to track each other. (Or the obvious joke: stalk each other.) It’s often extremely handy. It eliminates the need for about 90% of communication about where we are or when we’re getting somewhere. And it’s amazing how much of our communication is of that sort: the logistics of getting around and meeting. Eliminating it frees up our communication for more flirting and other good stuff. Very Future.
