Smartphone may be replaced by a credit card size card containing SIM and other important data. You slide your card in any internet connected device it becomes your smartphone. Your headphone connects to the device through Bluetooth. Your music streams from cloud storage, you can access your pictures and data from cloud storage, your apps and game automatically show up on the device you are at. You can chat, use message apps, make phone calls etc. In the long term, I don’t see a need for a smartphone.
