We're reaching a point in society where one will not be capable of achieving basic daily tasks without a smartphone. I went to get my hotel room key-card fixed since it had expired and the front desk was really pressuring me to use my smartphone as a digital key-card via the hotel's app and they were making it seem as though they were trying to move away from physical key-cards. I see contactless payment everywhere. I could easily imagine that in 10 years time everything goes to digital processes via smartphone or other "smart" device. And if you refuse to be apart of that system then you're simply out of luck.
