In your country, maybe. Over here you're dead in the water without a smartphone — can't access banking except by going to the branch and standing in the queue for an hour or two, can't access most government services. Limit your selection of goods (like electronics, but not only that) by something like 90% (and also increase prices by 30-50%) because brick and mortar shops sell old crap at much higher cost than it was ever worth, and the only real solution is buying from a major marketplace which is only available as a mobile application.

This concept originated in China and is spreading. Beware.
