id.me - With the push to get people on id.me to pay federal taxes in the US, I can foresee this eventually being a hard requirement to do anything related to the federal government initially and then eventually required for all state government interactions. Then I foresee this data being "leaked" on purpose to be shared with organizations that should not have it and just like Equifax they will barely receive a wag of the finger.
Network Connected Vehicles - This is already a thing. At best this will result in peoples cars being bricked by skiddies. This can be used to real time control where people can drive. People will have to start paying to "unlock" services in their car that is normally a function of a car. e.g. Get a pop-up that says one has to pay to use the window defogger. At worst this will turn into a dark-web business for targeted assassination or used to silence people that are speaking out of turn. There are some videos of peoples cars doing bad things and the driver fighting for control and ultimately losing. I can only hope more people implement their own private CCTV systems not tied to any clouds to document more of these.
Personal Social Credit Scores - All manor of companies are signing onto ESG believing they will benefit financially by signalling good intentions. Some stock monitoring sites are already factoring in ESG scores. I foresee this devolving into personal social credit scores that would manipulate public behavior and ultimately anyone not aligned with the system would be ostracized from some aspects of society or at least business. This will tie into the above Network Connected Vehicles. Park near a bar and get on a watch list for potential alcoholics. Park near a strip club and your spouse starts getting pop-ups for marriage advise. Walk past a digital billboard and be publicly shamed for being out of alignment with group-think, then be mocked by the billboard when your heart rate increases as per your body monitor. Score goes low, insurance and rent costs will increase, social benefits decrease.
Social Media Algorithms applied outside of the web - Social media organizations have already jumped the shark and many are finally catching onto this. This will start creeping into "smart" devices to manipulate people. Body monitors, smart home systems, AR headsets, etc... Facial recognition will tell the billboards and local businesses who you are, how much money you have and if you are aligned with correct-think. Monitors in police cars will identify people and show their social credit score, who purchases weed, who may be armed as they are driving by.
