The Ethics of Tracking

We've mentioned implanting chips in pets and even children multiple times in class, and each time we reached the issue of ethics. Is it wrong to implant a tracking chip in a child without giving them the choice? If, in the future, we were  able to develop technology like the grains in The Entirety of You, the ethical debate wouldn't be such a huge problem. When a child is old enough, they can be given the choice to turn their tracker on or off through a mental process, just like the characters in Entirety could control their grains through eye movements or the use of a small remote. It might be difficult to determine a set age, but it would give give children a sense of autonomy without fearing that they never had any privacy. However, if they were to be caught in a natural disaster, kidnapped, or in any dangerous situation, they could activate their tracker at will. The ability to manipulate the tracker through eye movement or a mental process would make it easier to activate than current technology like a 911 call, and it's much easier to hide. It would also be difficult for an assailant to remove the tracker, especially if it was in a place on the body more difficult to reach than behind the ear. I imagine these would be difficult to track in some areas just like how cell phones are difficult to operate in certain areas. However, I believe Dr. Johnson mentioned in Wednesday's class that the range of cell phone towers can be changed by the companies that own them, which would make this a smaller problem. I realize that we are probably far from this technology, but I don't see any breaking news about robots with artificial intelligence high enough to take over the world like we keep talking about in class, so I think it's safe to say my idea is plausible.
