It isn't that I don't trust technology I use it every day, however I've spent most of my adult life in the military and it is good to have backup skills. I've seen too many people that don't know what to do when the technology fails them. I carry a GPS but I carry as well a map and compass when I hunt unfamiliar territory. Never had the map or simple compass fail but your can't always rely on a GPS to work. Murphy happens and just because you say it hasn't ever happened yet to you that is fine but it doesn't hurt to have a backup plan.
If you remember or read the OP's original post he wants a rifle that can be used in AK big difference from the climate in AZ. Brown bear and moose hunting is usually done in some of the wettest areas of Alaska. Quality optics and rifles usually fare better than electronics in this environment. I have hunted SE Alaska where it rains over 200" a year and ziplock bags are your best friend for phones, but stuff happens and you can easily damage a cell phone.
Not to mention you could be days from ever getting your phone recharged. If you stay out in the bush you'll be lucky to have a power source to charge a cell phone at some camps. You can always carry batteries, but you might have to save weight because you are flying into the bush. Or you might want to leave your cell phone behind because it won't work anyway and rent a satellite phone for emergencies instead.
Technology is great and I'll continue to use it, but sometimes simple things work just as well if not better.
