By 2030 I expect there will be AI that can digest most publicly available information about a person and then from that generate somewhat accurate but 'privacy violating' inferences. This is already somewhat done by advertisers, but I personally could not type a name and get back accurate, impressive results.
I've tried this before on myself on one of those sites that promises info about a person, and it got lots of things wrong, didn't link to most of my public writing, and offered no analysis.
I will test on myself, and will resolve YES if it gets just a few things right but has appropriate confidence levels. For example, can it accurately estimate my networth (large error bars okay), or describe my personality, politics, and dating history? Something even creepier like can the AI somewhat accurately simulate me for a conversation would also resolve YES.
If I have to pay to use the AI, that's fine, but after that there needs to be minimal work involved on my end. If I have to help disambiguate that's fine, if I have to provide data or links myself that's not fine.
This should work on the average American, who has some social media history and public records.
