What AI and Quantum computing can do with MASSIVE datasets is amazing - find deep-level ("hidden") data, anomalies, relationships, and corellations that would never have been found, or would have taken a very long time to find, with older methods of data analysis.

Things like facial recognition; cell, text and internet traffic; geolocation info; financial info; and postal info have allegedly been gathered for years.

And, who knows what more advanced technology they might have as their technolgy is more advanced (est. 10 years) than what's available for public use.

IMHO, they have more data on each of us and more ability to mine it than we'd ever want to know. And, they have people for whom data and analysis is their life.
