Yup, came to say this.

Kids have learned to walk places on their own without maps or satnav or tracking for hundreds of thousands of years. I believe everyone would benefit from that continuing. We don't teach kids that the only way to do arithmetic is with a calculator... they learn first, then get a tool that can support what they already know. Why do we think we should do it differently here, and train this learned helplessness without a phone glued to your hand. I suspect a lot of this is projection of the parents' own discomfort with being away from their phone.
