If you are longing for a world that you never lived in, there's probably some "grass is greener on the other side" in play. The world before smart phones was considerably worse. I bet that most of the people who are asking for this don't know how to read a paper map and have never seen a phone book. They aren't considering getting lost or into a car accident and needing to find the nearest house to ask a stranger to call emergency services on their land line.
The good news is that, if you don't want to use a smart phone, you can just... not. Nobody is forcing you. If you really wanted a world without smart phones you would already not be using one!
