For those who think the NSA the worst invader of privacy, I invite you to share an afternoon with Aiden and Foster, two 11-year-old boys, as they wrap up a Friday at school. Aiden invites his friend home to hang out and they text their parents, who agree to the plan.

As they ride on the bus Foster’s phone and a sensor on a wristband alert the school and his parents of a deviation from his normal route. The school has been notified that he is heading to Aiden’s house so the police are not called.

As they enter the house, the integrated home network recognises Aiden and pings an advisory to his parents, both out at work, who receive the messages on phones and tablets.
