Would I use it? Probably once just out of curiosity. Do I think I'll see it in my lifetime? Not a shot. The odds of someone gaining access to all the data in all the services I use/used have to be close to nil. Companies aren't going to give up their user data, that's their bread and butter. Each service will need to have custom extractors written, and likely rewritten in a never ending game of cat and mouse. That's even if you don't get sued for accessing their systems to extract their data they have on your user. Then the storage required if you are able to get all the data. I requested my data from Apple a few years ago. It was something like 10GB of information. I assume shopping, social media, fitness, vehicle, mapping, etc. services have similar amounts of data on me. I wouldn't be surprised if the average digital identity has 1TB+ of data associated with it. Then, you have to normalize all the data. Each service is going to have the data in its own format with their own nuances that'll be a huge pain to get to a singular searchable format.
