Parents have a lot to contend with as it is. Making live easier by preventing the temporary loss of a child and the anxiety for both parties is a benefit.
If anything this gives kids more freedom, anyone not understand this should have a set of kids first.
Well if you decide to create rules to remove freedom and then say "you can only get your freedom back with this device I'll force you to wear" and call that "more freedom", we have different definitions. You could let them go to the same places they will go with the watch already, you were the one limiting freedom, not the absence of a watch.
Learning how to deal with anxiety in limited doses is an important part of childhood too.
> If anything this gives kids more freedom
I hope you're not too optimistic there. If it lets kids roam around outside more, than the upsides massively outweigh the downsides. But that's a very big "if".
I am speaking from experience as a father of two.
The watch teaches the kids to reach out when they feel overwhelmed.
They are fully in control of their own destiny. They don't always end up where they planned they were going and that is perfectly ok for me because they can reach me if there is an issue.
Should I just quote my adjacent reply that I guess you didn't see? "Even in that situation, at most you need some way to get a location at that moment when they chose to reach out to you, not tracking."
And the ability to get in contact is 90% of the benefit.
