imho, we as a society have been rushing/forced to embrace new technology without really understanding the downsides. I use nowadays cash as much as possible. The notion that every single mundane payment of mine is being monitor, tied to some profile and bid in realtime terrifies me. And no, no payment provider has ever promised me that they won't do this. We had also cash cards in the past in Germany, to my understanding they would provide digital payment without tracking and central control, but they are deprecated.
