My smartphone functions as a watch, notetaking device, and communication device. I rarely get lost now that I almost always have a map. It is a music device, which is really helpful considering I walk and take busses for most of my transportation.
The sole reason I've not had to carry around a wordbook is because I have a translation app on my phone.
It is much easier to choose to not carry a purse or bag, which sometimes makes me safer.
Not to mention that I have internet on my phone, which is better than phone books ever were. Looking stuff up saves money and time if you use it correctly.
You shouldn't expect folks to talk to you at the grocery store: That wasn't exactly a universal thing everywhere. Seems like this is just you missing something that others don't - and not everyone needs this stuff to fill their social interaction quotas.
