That's the wet dream of families like the Waltons, and is kind of happening already.

I was in a Wal-Mart last week and the front end lead I was talking to looked at her company phone and said that she had to come right back.

The store system cameras spotted something on the floor and messaged her, as the closest employee to the thing, to go pick it up.

I was astounded.

Wow, thanks for the link. How prescient was that writer - even the parts about using GPUs weren't too far off the mark! A depressing vision of where we're headed if something isn't done about it.
