Technology

This is like, the opposite of old-fashioned. Calling your wife when you're on the way home is old-fashioned.

This article is the first time I'm actually hearing about this idea because it never even occurred to me as something people would actually want to do. I frankly don't see the point of this nonsense. I would much rather talk to my wife on the phone and communicate with her about plans. It's much more human and normal, and facilitates good communication habits. It takes 2 minutes to give my wife a call and, you know what, I get to talk to my wife! We don't need technology invading absolutely every aspect of our lives. We don't need to be constantly plugged in and attached to our phones at the hip.

It also has other downsides, like making it hard to surprise your partner, constant battery drain from the constant location chatter, etc. In fact, it seems like all downside with no actual benefit (setting aside the trust stuff, because it's pretty irrelevant either way).
