People just don't realize how much power of abuse all this data provides in evil hands. Take smart phone location data. Some time ago, there was an uproar when the move-fast-break-laws company Uber published an analysis of how many of their clients in New York City had probably a one-night stand - based on their location data. A breach of privacy, sure.
But think about this: Google is collecting all this location data all the time, and storing it permanently. Finding out who is probably having an affair while their spouse is away on a business trip is essentially a database query for them.
Or another thing: It is well known that the animal most dangerous to single humans is other humans hunting them. The unspeakable hunt on Europes Jews is an example from hell but depressingly, there are many more cases in human history, like the witch hunts or the catholic inquisition.
Now, if things got too hot, people had the last resort to flee and simply disappear, going to a safe place where nobody knows them. That was the thing that saved Salman Rushdi when he had to flee Iran.
But in an ultra-connected world without privacy, this is not possible any more. That's because companies like Facebook, Twitter/X and Google have your social graph including your family. And even if you would never would give these companies your address in Rushdie's situation, a family member who has your address on the phone would happily upload his or her whole address book to Facebook or Google.
That's not a theoretical consideration - being ratted out by social media was the way many people in Syrias civil war (fuelled by Russia) died.
