The tweet: 
The game is called geoguessing and those who do this regularly are crazy good at it, taking into account the kind of trees you see, where the sun and shadows are, even the color of the dirt and the pavement.
Tom Scott did something similar and was frightened too: https://www.youtube.com/watch?v=cGqEBvlmFAQ&pp=ygUSdG9tIHNjb3R0IGZvdW5kIHVz
IMHO insurance is another thing. If the insurance company has reliable (statistical) proof that I live in a neighborhood where, for instance, my property is more likely to get damaged, then it’s only right (and fair towards the other insurants) that my fees are higher.
Living in a poor neighborhood, on the other hand, does not imply that I, personally, am less likely to pay back loans.
In Germany there’s a private company called SCHUFA that aggregates data about people, mangles them in a proprietary (i.e. secret) way and produces a “score” indicating how creditworthy an individual is. Companies buy these scores from SCHUFA, that’s how they make a profit.
One of the data points influencing the score is a person’s address. If you live near people of whom SCHUFA thinks they’re not creditworthy, your own score will drop, too. So by simply sharing their your address, you may already suffer detrimental consequences against which they have no recourse.
This is another instance of the “being put in categories you don’t want to be in” point in favor of privacy.
I didn’t find that in the Twitter UI and wondered why OP thought it was an AI. Thanks for sharing.
