AI would need far less data points to achieve an acceptable result, and maybe even be able of fingerpointing, not just fingerprinting. Just wait and see how the data broker bros start selling AI assisted data mining for ads. Big tech is doing that already. It's mind boggling how everyone seems to be just OK with that.

What AI can sometimes add is automatic feature extraction. Rather than having a to have a human explicitly think "I bet we can identify people via $x" and writing bespoke code to do it. E.g. this has been the big deal with AI in medical diagnostics, that it can look at the same data a very skilled human doctor sees, and still manage to discover something that the human couldn't, due to unnoticed features

Yeah but we've got old techniques for that too, Latent Dirichlet Allocation etc.
