Most people need a smartphone at least for google maps. Do you really believe people will go back to using paper maps for orientation? Or fixed phones?
Paper maps aren't that hard to get. Whether people will use them has no bearing on whether people can, and therefore they want the convenience of smartphones but only need verbal/paper directions when trying to get somewhere.
It's hard to say something is a "need" if it has existed for only 18 years and still has viable alternatives. That doesn't mean it should automatically be discarded, but it's disingenuous to act like it's actually necessary.
