A tweet can reveal your location, an Apple Watch monitors your health, a grocery chain loyalty card allows the supermarket to track your purchases.

A little over a year ago, U.S. President Donald J. Trump’s third meeting with North Korean leader Kim Jong Un was making headlines as much for its historic nature—it was the first time that a sitting U.S. president had set foot in North Korea—as for what it represented about the lack of progress in U.S.-North Korea relations.
