Would you mind posting your phone book and a copy of all your text messages here for us all to read? Can we see your photo album, all credit card transactions, amazon purchase history, GPS location data, credit score? We promise only to sell this info to other people, use it to sell you stuff, raise your insurance rates, tell us where to focus our funding for political campaigns. Don't worry, we'll only save it forever and you can be assured that we'll feed this into AI models 10 or 20 years from now, along with everyone else's data, establishing a massive cache of information from which incredible inferences will be possible. We may or may not use this information to enrich ourselves, increase wealth inequality, influence politics. You should surely not take steps to limit the data being collected about you. Just relax your body. Let it happen.
