1.) I do not think it would be hard. Because you would already to be used to living that way, so it might actually be easy.
2.) Absolutely. Technology is going to advance forever because of how many things people want to make better, or make better of someone else's technology.
3.) For me, it doesn't bother me. Im usually working, hunting, or hanging out with friends, so the only piece of technology I really use is my phone.
