The bottom line is the world is changing rapidly to an exclusively electronic/online mode of communications and commercial interaction. Paper documents and cash will be stuff you see in a museum. You will need a smart phone for basic life functions from purchasing a container of milk, reviewing resumes from a shadchan, making an airline reservation, paying the bus-fare or communicating with first responders.
Meanwhile, many can manage without it and avoid the dangers. Daya l’tzara b’shaata.
Hard copy printed seforim will be phased out and electronic versions on tablets will take their place.
I guess you don’t realize this, but frum Yidden don’t use these devices on Shabbos or Yom Tov.
