Similarly, mass spying will change the nature of spying. All the data will be saved. It will all be searchable, and understandable, in bulk. Tell me who has talked about a particular topic in the past month, and how discussions about that topic have evolved. Person A did something; check if someone told them to do it. Find everyone who is plotting a crime, or spreading a rumor, or planning to attend a political protest.

Spying has always been limited by the need for human labor. A.I. is going to change that.

This is something I've been harping on for a while. AI models are getting small enough to be run on our phones. Most of our data is not encrypted and apps and aggregators now have the capability to summarize and leverage our content in very novel ways.

In fact, when done right, this is going to be mass spying in a completely privacy preserving way. What they can do is just create embeddings of our data on-device and then leverage them for different ad-serving purposes.

The next age of ad-tech is going to be freaking-wild.
