What happens if your battery dies? What happens if you drop your device and it breaks? How are you going to cope? Are you going to miss your 'once-in-a-lifetime' job interview?
The sort of dependency you describe ("emotionally hurt", "life damages") is foreign to me.
I drove from FL to UT and back a couple of years ago using only my iPhone for directions. I did not get lost once, even though we went through twenty different inner-cities and camped out in National Parks for weeks. Currently Apple Maps has my house city and my work location wrong. I live in a heavily populated county in Florida (Pinellas) and if my local directions are so wrong, I don't know how wrong the remote destinations will be.
I can understand why you don't need to trust your GPS or care much about directions if you've lived in the area for long or have good public transport. But just like many people rely on cellphones for voice calls, many people rely on GPS that comes with cellphones. I can accept change if it is better, not worse. I'm used to my cellphone GPS being correct. I'm not used to it being wrong.
Try going somewhere important and missing it because of a Maps error, and you'll sing a different tune. You might not be "emotionally hurt" but you're sure be pissed off.
