In 1997 J.K. Rowling, in her first Harry Potter novel, introduced us to a fictional universe in which people can wave at you from newspaper photos, maps can show you where people are at the moment, and various other fantastical possibilities. A quarter of a century later, we take many of those very same things for granted in our everyday real lives.
Suppose you wanted to invent a magical fictional universe today, and you only wanted to include “impossible” things that will actually become everyday reality in another twenty five years. What would you include?
A cloak of invisibility that doesn’t really make you invisible but allows you to go about your business without leaving a trail. In other words, it hides you from everyone else’s real-time maps. It would allow you to conduct transactions that cannot be traced or analyzed; to converse with friends and family with complete assurance that nobody is listening or recording; and to consume media without others keeping track of what you’ve watched, read, or listened to.
Also, a “magic wand” that you can point at factually incorrect information about you and have it corrected. Furthermore, those corrections would magically spread through the ether to correct all of the other datasets that have replicated the same errors. It would be especially useful for medical records, credit reports, utility bills, voter registration roles, building permits, etc.
Teleportation.
