Remember when phones were to carry on conversations? Then came cell phones with cameras, and the talking function competed with snapping pics. Then came apps.
Many of have a peek-hole in the front door so we can see who is ringing the bell or knocking. Not Sara and Ben, in their new home. The door has a small touch panel with a code, which triggers an app on either of their phones to let them know someone has arrived. There’s also a camera, which shows them specifically who is at the door. I’m sure they can talk to the person, without opening the door at all.
They can also control their entire heating and cooling system from another phone app.
I think the thing they probably do least with their phones is talk on them. 🙂
